- Hope given back

Listening to these men sing brings childhood memories back and all hopes and dreams of the 90’s/00’s back! Love that they kept their style but was able to modernize it! Wish I could see them on tour, but baby is due on their concert date for my state 😭

- Love BSB!

They still sound great! Happy after all these years they decided to do this journey again!

- The best

Backstreet Boys at their best... a combo of old school meets modern times with this album! I love it!

- Cool

Good music and it will not get old for me. Would like to hear more upbeat again such as songs in Backstreet Boys and in Black and Blue albums.

- Will the real Backstreet Boys please stand up!

Way too generic and boring. Where’s the excitement, the upbeat songs you can dance to. The only one that sounds decent is the first one but even it doesn’t sound nearly as good as many of their other songs from previous albums. Stop following the crowd of modern day pop songs and stick to the good kind of pop that everyone is used to and loves about you guys. Or at least the same style of slow songs you guys would make back in the 90’s. At least those sounded a lot better than this (example: drowning-slow but epic and the words actually mattered).

- THEY’VE DONE IT AGAIN

As a fan from the very beginning, I own every single BSB album and have never been disappointed. DNA (in my humble opinion) is one of their best albums if not their best. I love how they mixed in new sounds yet still kept their signature sounds. I can listen to the entire album without skipping any songs. My favorite songs are Chateau, Ok, and New Love. I can’t wait to see BSB in concert this summer!!!!

- Love it!

Such a great album and after so many years they still have an incredible sound!

- I’m literally in SHOCK!! Their best album by far!!

Their best work yet. Lyrically, Vocally and the harmonies omg!! Great beats and arrangements. Lots of growth. Mature but yet still fun. This is the album they should of done right after Millennium. Must buy!! 🔥🔥🔥🔥🔥

- Love

Love every song!

- Best band in the world ❤️ They never disappoint me

Loving every song ❤️❤️❤️

- One Word:Fire! 🔥🔥🔥🔥

Mature,“Grown Folk” music!! Their sound has matured just like fine wine. I have always been a fan and will continue to be one. I can’t wait for their concert this fall.

- Sleepy

I was really hoping for more upbeat, fun music. This is all very slow and not exciting. The songs are not keeping my attention the way they used to. I wanted something more upbeat and dance worthy. This is a bit sleepy.

- BSB RULES!

They never disappoint. Loved them in the 90’s and continue to love them more and more! ❤️

- I love these boys!!

Soo good!!! Has some really catchy songs, especially “Ok”!

- Love it

Love this album ! One of the best!!

- Awesome and classic

Sounds as good as always!! Great job guys!

- Best Album since Millenium

I haven’t liked a BSB album this much in quite some time. All of their voices sound so powerful, and full of Character & Emotion! Songs with great rhythms, especially Passionate.

- Doesn't have a song I dislike

Been listening to the album since it came out, also saw them in the DNA concert tour (and Vegas), and I've come to the conclusion that there not a song I dislike on this album. The last two songs are my least favorite -- but by no means do I dislike them or even skip them. I've been a fan of BSB from the beginning and have always enjoyed thier albums (even the later ones people who aren't big fans forget exist) but on those later albums I definitely have songs I skip. This one is up there with their best albums for sure. I have old songs that I like more, but this collection is fantastic and I hope the new follows this upward trend! (Also I wish we were able to buy the Japan exclusive bonus tracks.)

- One of their best!

Definitely one of their best albums. There’s usually a song or two on any album that I could do without, but BSB nailed every song on this one. Truly talented & they all fit perfectly in this group.

- In love

I love this album

- it’s okay

Been a fan since 1997 and I’ll say this album is OK it’s just sounds like they’re trying to catch up with the new pop artists instead of sticking to their own style in their classic almost like they’re trying to be something they’re not and I only like three songs on here and that’s it. it’s like old man trying to be cool and hard instead of just keeping it natural.

- NEVER GETS OLD!

Born in 92. Still love these guys and create goood music still! Awesome!

- Will always enjoy!!

I grew up listening to these guys!!! They’ll always be one of the best boy bands out there!!! I’m so glad they are back!!!

- The best boyband ever

Im so in love with yall, one of the best albums ❤️

- Fire Album 🔥🔥🔥🔥

This album is straight fire! 2019 and yet they still making solid music.. their album has been on repeat all day!

- The next Millennium!

If you were a BSB fan in the 90’s, you have to get this album! It does not disappoint. Twenty years have gone, but they still make you feel all the feels!

- They’ve still got it goin’ on

Words cannot express the happiness that these 5 voices bring me. Every time I listen to any of their albums, I’m in a good mood. This album is no exception. They have made the music a bit more “modern” but they are still the Boys at the core. “The Way It Was” and “Just Like You Like It” are probably my fave songs on the album. And HELLO KEVIN! Where have you been hiding all these years? I may be wrong, but it seems like Kevin has a few more solo-bits on this album. Can’t wait til August!

- Very impressed!

Solid album. My highlights: New Love (ultra 90s vibes!), No Place, Don’t go breaking my heart and chances. It’s probably their best album since Black and Blue. Good job guys!

- Good album but....

Ok guys, been a fan since day 1, and have evolved with you through the years, and while this is a good album, it's missing the upbeat pop jams that we love from you. "Don't Go Breaking My Heart" is such a great pop masterpiece, I was certain we would get a few more songs in similar production and sound. But the rest of the album is, well, just O-K. While there is a few good songs here and there, nothing compares to the first single of this album. (Reason while it was a hit). I hope you come out with another banger this year.

- Amazing album!!

There’s only a couple of songs on here that I’m not diggin but everything else is amazing!

- 30 years strong

Got to see them in concert for dna tour what a great time now with family this past summer it was memorable!

- Love it!

Although I was not even born yet when they became a group, I love their music and this is such a good album! So glad they are back!❤️❤️

- Same Great Sound, New Musical Innovations

I love the album! I’ve been a fan for over 20 years. I first saw BSB in 1999. They have brought some fun new vibes to their music. Thanks for the great music and hard work on DNA.

- BSB is still awesome!!!

I love the new songs from BSB! They sound as great as ever and they harmonize so well! My favorite group! Their old hits are still my fav, though!

- In love

They never disappoint me love the album love my boys so glad they did a come back I feel like a kid again

- Obsessed

I love it! This is all I listen to in my car. I can listen to the entire album without skipping a song. Breathe might have to be my favorite song. It definitely has their 90s vibe.

- BSB

Sorry my least favorite of theirs. Didn’t like it at all.

- Wonderful comeback

I am completely obsessed with this album. I cannot stop listening to it. I love every song. My favorite is Chances and No place. But seriously love every song. I’ve been listening to BSB since they came out when I was a young kid. So happy to have them back. Great job guys!

- Can’t stop smiling!!!

I always knew this day would come. And now another GRAMMY nomination!! 20 year fan and just so proud of these guys. They have stayed true to themselves, their music,their families, and their millions of FANS!!!

- Overall great!

There were two songs that I had to let grow on me, but it's BSB! I love how everyone's voice is in most songs now. They even put an acapella song on there for us old BSB fans who fell in love with them that way.

- Horrible message

New Love is a horrible message for our youth especially to our young girls. Basically saying that one night stands is normal and that it’s ok to degrade our young girls. BSB is usually my guilty pleasure but not for this song.

- LOVE

💕💕💕💕💕

- Backstreet Boys

I’m excited about the Backstreet Boys. I love all song. But my favorite song will have be chance and don’t breaking my heart

- Still the best!!!

Will always love them and their music.

- Awesome!!!!

I love Backstreet Boys sooooooo much

- 🤗🔥

I have been a fan since the very beginning and this CD is by far the best since Black and Blue! I have been listening on repeat since it came out and can not wait to hear it live on the floor in Orlando this summer!!!!!! Favorites are Nobody Else and OK ❤️

- Perfect!!!

They can’t get any better. Love them. My favorite boy band of all times.❤️

- 😍😍😍

Missed them and I’m so glad they are back with these great album. They are an awesome group and they always will be

- You Rock BB

- The best

I love this album front to back. 1 of the best since Millenium.

- Impressive!

Man.. the boys took some serious chances here.. toying with genre cross-breeding , bringing a splash of country rock into the mix, and some very Indie folksy flavoured pieces. Does all work together... absolutely! They pulled off the ever-elusive comeback comeback, rarely seen in today's industry. Now the big question... can it swim in these new waters? The lead-off single is so strong (with nuances of hip-hop and RnB interwoven into a mindblowing mix, then set ablaze by a state-of-the-art production team), that I have every confidence they will find their way back. Good luck gents! Always a fan. =)

- I am in love with the song chances.

Love the song chances. Just a little bugged by the fact that they have another song with the title breathe. Other than that love the album. Two songs with the same name make it hard to request the right one. Still love my BSB.

- BSB

I was disappointed in their last album but this album is amazing they went back to what makes that great. No place is probably my favourite track

- Yeah boys keep it coming

So good I love it

- Killed it!

Great tracks!

- So many good songs

I haven’t cared for the last few albums, but this one is really good and not cheesie poppy

- BSB DNA

BEST ALBUM EVER!!!!!❤️❤️❤️❤️

- New and hot

Nine albums later, never gone on hiatus or taken time off, this band has now evolved with what's trending in music. I HIGHLY recommend, The Way It Was.

- DNA

Ok i’ve been a fan since the 90’s and this album is giving me all the feels!!! Can’t wait to see them again this July!!

- Just go away

Never were good or talented....still not

- Amazing

Listening to the album and so far there is not a song I don’t love! ‘Just Like You Like It’ is one of the hottest songs I’ve ever heard! Should be an anthem. ‘No Place’ is a beautiful love song. What’s nice about The Backstreet Boys, is their songs have great lyrics but also music that makes you want to move. Listening to a few songs just made me go from terribly sad to feeling much better! Must Buy Album!

- Amazing

The boys put so much work into this album and you can tell! Every song is absolutely fantastic! Buy it! You won’t regret it!!

- Close, but not quite the same

Nothing like 1999/early 2000’s. Two or three good tracks, but they’ve tried to adapt to a new sound which doesn’t suit them. It could’ve been so good if they kept it simple, and didn’t abandon what has made them great.

- popdude13

Great music guys, you all sound fantastic. Such a great sound.

- Literally 15 seconds...

I have been a Backstreet Boys fan since the beginning and I am SO GLAD my sister and I saw them in concert for the reunion tour with (mostly) the old songs because their new stuff kinda sucks. This album is a total disappointment. I literally only like the 15 second chorus of track 4 and that's just about it. Where is Brian!!?? He used to be the main singer and now you hardly hear him at all!! It's like him and Howie traded spots and I do not approve. Howie's high singing makes me want to change the music. BUT...those 15 seconds, totally worth the listen!!!

- Amazing

Amazing!!!! Love the new sound, it’s like 1999 all over again!!!

- I got a new love!

I’ve been listening to the album since it came out. Catchy songs. Wasn’t quite sure what to expect from this album but I like it! Remnants of the bsb of the past with an update.

- I LOVE IT!

One of their best albums. Breathe is absolutely beautiful. Passionate, New Love and The Way It Was are on repeat! The singles were all great! Do yourself a favor and give this album a listen!

- Love it. They never disappoint

Love it. Some original song and some new sound. Couldn’t be happier. Can’t wait to see it live.

- BSB

Amazing , they still have their stride.

- Shrek

Absolutely love, all songs are flawless

- The ultimate comeback

What's good Backstreet Boys? DNA (including: Don't Break My Heart, Chances) is a good and pure pop album. This year, world tour, Canada waiting for you. WE LOVE / ON VOUS AIME

- They never fail to impress me.

I cannot stop listening to this album! It has everything from pop to country to R&B. It is absolutely beautiful.

- Love all songs!!

🥰!!!!

- Refreshing !!!!!!

I love this album. Have it on repeat

- BSB

New love & Passionate 👌🏻👌🏻

- Perfect!

BSB have never disappointed me. I love these guys!!

- That is why they are the Backstreet Boys!

One word "beautiful" album. They never disappoint their fans from all over the world. They are simply the backstreet boys.

- BSB forever ❤️❤️❤️

Love all of the songs! Absolutely “No Place”.

- Amazing!

All the songs are awesome so far. Just listened to Breathe for the first time and I love it. It's great to hear them sing without all of the music. Makes their voices stand out more. I expect the rest of the album to be great too. Can't wait.

- Amazing

What I believe Angels must sound like

- They just keep getting better!!!!

Every song so far has been so good! Can’t wait for the rest of the album!! ❤️🎼🥰

- Finally

So happy BSB found their sound again! This is what they are about! I have been missing this in the past two albums. Welcome back boys 😬🤘

- Sophie ❤️ BSB

I was there first in montreal, and i’ll always be there now with my family! ❤️

- It’s been a long time coming to this

I was on the BSB Cruise in 2018 and heard some songs that had the potential to make the cut to DNA. I’ve been counting the days ever since to hear Passionate again! Can we be January 25th yet? And please, don’t let us hanging another 5 and a half years before the next album, fellas! ❤️

- BSB Fan since the beginning

So looking forward to this album. BSB you’ve done it again. I will always be a fan.

- fan since day one!

this album has made me fall in love all over again with BSB! fan forever!

- Awesome

Best song ever!!! So obsessed 🥰🥰🥰 the boys out did themselves for sure

- “No Place”

LOVE this song!

- So far so good!

I gotta say i didnt think these boys had it in them. The first song was great and the video choreography was silly, but kinda worked. Keep pushin them out boys.

- A secret fan.

As a 37 year old man. I have a weakness. It’s the cheesy pop music Of the BSB. Lol.

- Terrific

If the first two singles are anything to go by, we're in for a treat!!

- 😍🔥🔥🔥🔥🔥

I’m going to be traveling for 16 hours to Montreal to see them in concert and I cannot wait!!!!!! Been a fan since 97’ ❤️❤️❤️❤️❤️

- Can’t wait for the album

Both songs released are amazing! So happy BSB is releasing such great hits! 25 years of greatness. Fan since day 1 ⭐️⭐️⭐️⭐️⭐️

- Loving these guys

Can wait for their concert here in Toronto next year 😍😍😍

- Love two songs so far.

This going be a good album

- 😱😱😱

I am so excited for this album! I really can’t wait. BSB FOR LIFE!

- Can’t wait for the album!

Been a fan since day 1 and will always be! Thank you for your music 🎶 I have grown up listening to you and I am a proud BSB fan forever. See you in the summer! P/S my 4 yr old girl love’s you too ;-)

- Can’t wait...

The first two songs are amazing!!! Can’t wait for the album in January!!!!

- Mature

Their music sounds very mature on the tracks that have been released so far....looking forward to the album

- BSB BACK, ALRIGHT!

Such a good album, already on repeat!

- Album of the year

Such a good album, can’t skip any songs.

- Backstreets Back Baby!! ❤️

Excellent album with the boys doing what they do best. So many good songs, totally loving everything on here but current stand out for me is ‘Breathe’. Can’t wait for the tour!! #KTBSBPA

- So excited 🥰

First three songs are amazing, looking forward to the hole album and a world tour, Plz 🤞🏻they come to Australia 🇦🇺

- LOVE THIS

Seriously, these songs are so good, experimental for them yet brings nostalgia and heartwarming feelings. I’m so glad they haven’t broken up like most boy bands. There’s a reason their music still connects, and transcends time and trends, they are classic.

- Title Write a Review Tap a Star to Rate

Review no yes red

- Legends!

These guys are masters of There field! I feel like a teenage girl again! Best boy band ever! Thank YOU backstreet boys for still making amazing music! Your music will speak volumes for decades and decades! Australian fan always ❤️

- Best album yet!

These guys just keep getting better and better with age! So it’s no wonder this album is no 1 on the Billboard charts! Thank you BSB for this incredible album.

- Not the greatest.

Unlike most of the BSB fans, I'm going to write an honest review. DNA, while it's new music, is pretty boring. I've heard it before. The Backstreet Boys, are known to be able to renew themselves each album. This one failed majorly. Let's throw songs together, that aren't really us anymore, just to please our fans. Who, I might add, at times are ungrateful anyway. Take more time to release the best album ever. This didnt hit that mark.

- Fantastic album

This is by far one of the best BSB albums I have ever heard. it’s a brilliant mixture of fast and uptempo and slow and smooth music. The boys still have it after all these years I can’t wait for them to tour

- ❤️

Falling in love all over again with these guys. What are the chances? One in a million. Just like you like it ❤️

- Back in their glory

This album is perfection. Every song on this album you can feel the passion and soul in what they sing. I haven't felt this since Black and Blue. The experimentation in different genres of music definitely worked in their favour. What is more genius is that they have included an a Capella track which was what they were originally the masters of. Move over Pentatonix they still have it.

- They keep getting better!

Been listening to this on repeat for the last 24 hours 🤗

- Backstreet’s Back Alright still 25 years strong!

Been a fan of their’s for around 23 years know all the words to their songs and even the unreleased ones. DNA really shows that they are no longer boys but more men. If you still love the old school BSB this album is much more Unbreakable than Backstreet’s Back but they still know how to sing and release an album and still dance at 40 years of age for example ‘Don’t Go Breaking My Heart’ Music Video. I would recommend listen to the previews before buying. Can’t pick a fave as I’m on my 2nd listen but every song are the best especially going Pentatonix (sorry if I spelt it wrong) with Breathe is a must listen especially to those who think they can’t sing. First time listening to it made me very emotional. Backstreet’s Back ALRIGHT!!!

- 2019 album of the year

Chance and Don’t go breaking my heart are outstanding songs! Can’t wait to hear the rest.

- Backstreet boys oh no

Have purchased this album and had a little listen so far the only tracks that are good are the ones they have already released. Others just don’t sound like them and seem like they trying to fit into another market. Stick to the hits you make abit disappointing hope the tour has more of the oldies on.

- KTBPA

Listening to this album makes me look forward to seeing them in June even more !! Can’t bloody wait!!

- 👌👌👌👌👌😍😍😍😍

Another outstanding album by the boys. Keep it up.

- Love these

Had every single album..... I love these and finally going to see them for the first time this year ❤️

- Backstreet is back

Absolutely loving the new sound of the BSB! They absolutely smash this album and I hope they keep going in this direction as they shine. Don’t go breaking my heart, no place and breathe are my favourite so far!

- Awesome

It’s funny how people think they have disappeared they never broke up they have always been around good album look forward to the tour ☺️

- They were never gone!

Actually they never ran out of money they have been working their asses off since before 1993!! Not only doing music, concerts, movies, directing.. cruising-making their fans happy BUT also taking care of their families! No forgetting Vegas residency (which is sold out) BTW they have enough MONEY they don’t need to do it for the money! Why can’t people just enjoy music and if you can’t then leave others to it!

- Joel

Absolutely brilliant full of tunes, can’t wait to see them at the o2 in June!!

- AMAZING

Love BSB! This album has a lot of feel good songs. They have stuck to what they are great at which is their harmonies and you can really hear that in their songs. They are truly the best band in the world.

- They’re back!! Better than ever

Amazing album from start to finish. 100% backstreet Boys quality

- Wow *****

What can I say!! I’m happy to go on record and say that this the Backstreet Boys BEST album! I’ve been a fan for 25 years and this album has blown me away! Some of that tracks are pure filth! ‘New Love’ & ‘Passionate’ wow!! Cannot wait for the tour!! The greatest boy band EVER showing all the others how it’s done!! Keep going boys, our ears need your music!!

- 😍

Best album since Millennium 😍 on repeat since Friday ✌🏻

- Great as ever!

Obviously someone who wrote a review here, doesn’t follow the Backstreet Boys and thinks he know what he’s talking about... It makes me laugh when people think they made a new album because ‘the need the money’. They have been performing since 1993 and just because you haven’t heard it, doesn’t mean it wasn’t there... This album has a bit of everything. It has some good old-fashioned pop, a bit of country (they seem to be into their country music nowadays...) and some up tempo music as well. Something for everybody (yeah)! Music is in their DNA and I, for one, am glad they made a 9th album!

- 🔥🔥🔥

I love the guys so much❤️after so many years without an album but this has been 3 years in the making! And I appreciate their hard work so much and honestly this album has changed they way I look at some things ❤️Also, this is amazing I’m obsessed, and I hope they continue what they love doing and what us fans love as well! ( Would highly recommend buying this it’s so worth it)

- Best album since Never Gone

Oh wow, worth the wait! Some of the album songs are better than the singles! Fantastic album!

- :(

Did not receive my code for the pre-sale for concert

- Backstreet's back.

Don't Go Breaking my Heart was incredible, and I can guarantee the rest of the album won't be much different. I can't wait for this to drop!

- Love is everywhere!!

The Best album so far! Love it as everyone can find a tune for themselves. Young middle age old...absolutely everyone Backstreet boys are like expensive and the best quality of wine... older- better! Do not regret even a minute from last 25 years I spend listening to their music! See you all on DNA tour!!!!

- 😍😍😍

Ohhh how I love these boys!! Can’t wait for the whole album I love this second release ‘don’t go breaking my heart’ was amazing this is soooo good ❤️❤️❤️

- Love it

I feel that it is simply amazing. All the songs touched my heart and soul.. thank you BSB

- dna 🧬

this album is amazing! keeping bsb style and making it more modern, what’s not to love?? my fav is new love haha🥰🥰

- Different sounds, same talent

I’ve been hooked on the backstreet boys since I heard them in 1995. This album sounds a lot different to back in the 90’s but time has changed and whilst they still need to be themselves, they do need to appeal to the ever changing music industry. I am proud of them being able to make their second self released album. ‘Nobody else’ has such good lyrics and beautiful vocals, one of my faves. I don’t love every song but they have delved into different areas and should be appealing to some of the millennials. I am glad howie gets more of a role in some songs, he has a beautiful voice and his falsetto is still on point 25 years later ❤️

- Backstreets back!

Love the first two tracks released on their new album! Can’t wait to hear the rest!

- Amazing

Another great album. Well done bsb

- 😍😍😍😍😍

LOVING the 2nd song from the new upcoming album! Made extra special by all the BSB boys on vocals!! ❤️

- Great album

Best album in the last year

- backstreet boys

perfect excuse of a band who ran out of money so got back together they are well passed there sell by date just dated and corny now

- Funky and fun

I’m loving this album. So much funk and screams summer all through the album. From start to finish this album shows why Backstreet Boys have such a strong fanbase. I’m loving this album. Fave songs atm are Don’t go Breaking my Heart, Breath and Ok. As I keep listening it will probably switch up 😂. Really really great album Boys!

- LOVE

It’s about time we got this album and they never fail to deliver greatness!! Well done Backstreet Boys!! Bring on the tour 🥰

DNA Wiki

Deoxyribonucleic acid ( ; DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life. The two DNA strands are known as polynucleotides as they are composed of simpler monomeric units called nucleotides. Each nucleotide is composed of one of four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A] or thymine [T]), a sugar called deoxyribose, and a phosphate group. The nucleotides are joined to one another in a chain by covalent bonds (known as the phosphodiester linkage) between the sugar of one nucleotide and the phosphate of the next, resulting in an alternating sugar-phosphate backbone. The nitrogenous bases of the two separate polynucleotide strands are bound together, according to base pairing rules (A with T and C with G), with hydrogen bonds to make double-stranded DNA. The complementary nitrogenous bases are divided into two groups, the single-ringed pyrimidines and the double-ringed purines. In DNA, the pyrimidines are thymine and cytosine; the purines are adenine and guanine. Both strands of double-stranded DNA store the same biological information. This information is replicated when the two strands separate. A large part of DNA (more than 98% for humans) is non-coding, meaning that these sections do not serve as patterns for protein sequences. The two strands of DNA run in opposite directions to each other and are thus antiparallel. Attached to each sugar is one of four types of nucleobases (or bases). It is the sequence of these four nucleobases along the backbone that encodes genetic information. RNA strands are created using DNA strands as a template in a process called transcription, where DNA bases are exchanged for their corresponding bases except in the case of thymine (T), for which RNA substitutes uracil (U). Under the genetic code, these RNA strands specify the sequence of amino acids within proteins in a process called translation. Within eukaryotic cells, DNA is organized into long structures called chromosomes. Before typical cell division, these chromosomes are duplicated in the process of DNA replication, providing a complete set of chromosomes for each daughter cell. Eukaryotic organisms (animals, plants, fungi and protists) store most of their DNA inside the cell nucleus as nuclear DNA, and some in the mitochondria as mitochondrial DNA or in chloroplasts as chloroplast DNA. In contrast, prokaryotes (bacteria and archaea) store their DNA only in the cytoplasm, in circular chromosomes. Within eukaryotic chromosomes, chromatin proteins, such as histones, compact and organize DNA. These compacting structures guide the interactions between DNA and other proteins, helping control which parts of the DNA are transcribed.
