- Hello everyone! Today’s video is all about DNA and chromatin, and this understanding is essential for then going on to study epigenetics (which is such an exciting field)! The time stamps are linked below as usual to help guide you through the video, and feel free to leave any questions down in the comments section down below! Enjoy 🧬

As a french teacher of biology, I am really impress of the way you explain. Yours biology videos are so interesting.
You teach very well !
I look forward to your next videos !
I'm studying 2nd of Pharmacy in Barcelona and tomorrow I have an exam about Molecular Biology and this video was really helpful!!
I like watching scientific videos in English because I would LOVE to study in England one day😍😍 (I'm a bit obsessed with your accent hehe)
This video is nice summary for my epigenetics exam which I am studying for now.
I just graduated high school, but I am watching this for fun :D
Thank you sooo much holly i really like your videos.
I love when you post on this channel, I learn so much from you! :)
Ohaa! Loved this video!
Literally screamed when I saw the video title. Thank you Holly for the awesome video! ❤
Tysm for another informative and interesting video holly💚💚
Holly!! This channel is so incredibly fresh in terms of the kind of content it brings. I really hope more people discover this channel. You put everything in such simple words that I always get so so consumed that i am surprised that I actually finished the video in one go. Great work you are doing here♥️ I love it and already cannot wait for all the content you’ll put here😁
I'm currently doing a project on cancer epigenetics on my internship totally love ittt 😭
This video was so helpful, thank you so much!
This is so interesting. I really want to study biology after graduating and this just proves to me that it is the exact right thing for me to do. Thank you! So excited for this channel.
HOLLYYY YOU SAVED MY VIVAAA ILYYYY😭😭😭😭😭
Loved it ♥️
I am a MSc Medical Genomics student and I recently came across this video randomly while browsing TH-cam genetic content.
I've got to say if that had been the way my teachers explained genetics in secondary school everyone in my class would have started loving biology.
Well done on the factual information and cool ways to explain!
Looking forward to more genomic content :)
I do biomedicine science and I'm learning English (I'm from Brazil) and you managed to combine the two things that I like in a single video. Thank you very much!
I got excited as soon as I saw your video..❤️❤️
Same
I recently studied about cells and their structure in school but it wasn't in detail bcz I'm in 9th grade. This makes it so much more interesting and I can't wait to learn more. Thank you Holly, for making biology even more fascinating for me.
I'm literally in the same situation
I love this channel and I really learn from your videos, also I've studied natural science but the way you explain these topics is so much better than any of my teachers so thank you so much💜
btw your channel's name is so creative, nice pick=))
wish you the best and I'm waiting for more videos..
haha ahh thank you!!!
omg love you! could you do more stuff on inheritance? its killing me in school :( I like bio but as a fan of botany related stuff genetics is making me hate it so so much
Till the time she posts more videos, I really recommend shomu's biology for all biology topics. He makes it really easy to understand
yes I will be creating content about genetics!!
perfect repetition for my cellbio exam tomorrow :)) thanks holly!!
no worries!!!!
Heeey Holly. I just want to say I'm absolutely LOVING your videos. I'm from Brazil, and I'm currently in college, to become a physical therapist. Not only your videos help me revise all the basics, but they really help me with my english. Great work darling, keep going 💕💕💕💕💕💕💕
ah thank you Luana! Good luck with you degree, you’ll be an amazing physio, and thank you for watching these videos!! ☺️💚
very well explained Holly👏
cleared all my doubts✊
made my concept stronger💪🏻
thank you💚
no worries at all ☺️
really needed this video!!! genetics stuffs are so confusing!!!
ah genetics, I feel you, my whole first year at Cambridge doing genetics was a crazy ride 😂😂😂
I am so glad that you are sharing your knowledge to us, its amazing how you can talk about what you love. I am doing biotechnology major, this was perfect to see the youtuber whose videos i like so much is also teaching the subject somehow.
I loooove love love sharing knowledge!!! 💚 and good luck with your degree!
I absolutely love how your videos are made. Im in my last semester of my biology degree and I understand everything you're saying and then there are students from 9th standard, who are understanding this too.
Truly versatile content
ahh this is so amazing to hear, thank you!!!!!
Holly I genuinely got the same interest as you in bio... I love epigenetics and immunology, too!
I study molecular biology and biotechnology, so this is nothing new for me. But I loved this video. Basics explained easily, so everybody could understand. Definitely continue in this channel. ❤️
very reassuring to hear ☺️ thank you!!!
Hi love the channel, please do biodiversity of animals next please😌
wonderful teaching holly your biology explanation is excellent I am a 14year old student I was wondering
1.if blood cells do not genetic material then how do they multiply or replicate
2. why is it that blood cells do not have genetic material or what would happen if it had one
3.how does a cell repress or turn off a gene and by what process
My a-level biology finals are in about 3 weeks and i have just revised this topic. The oral exam will either be about genetics, ecology, neuro biology or behavioural biology and I hope i'll get genetics or neuro because it is way more interesting. I love this channel and your main channel as well! 😊
getting the topics that you hope for is the best feeling ever in an exam!!! good luck!!! 🙌🏻🙌🏻🙌🏻
@@byhollyg thank you so much!🥰
Holly please teach on meiosis and mitosis... Pleaaaaseee...
Holly, could you please make a video about interphase and cell division(mitosis)? I'm sure a lot of people would love to see that video...
yes sure! the cell cycle will be coming up shortly!
I know you didn’t take that teaching job in the past, but those kids and school missed out on having an amazing teacher! You are so engaging to watch and have the amazing ability to teach something complicated in a “simple” yet detailed way. I don’t care if you post only once in a while on this channel, I love these videos! I actually going to get a notebook to take notes just because I love learning this topic. Thanks Holly!
I love teaching, and in some ways this is the best way to do it! I get to use what I’ve learned from vlogging on my main channel and just throw in the educational content 🙃😉
also, thank you so much for your support Vanessa! I really want to work on this channel alongside my main one because I’m loving it so far! 🙌🏻🧪
Hey holly,plzz tell about chromatin looping..lots of love from india🤗
Now this is biology!
yes it sure is 😉
