DNA Packaging

[TheGreenLing]

Higher level summary for those who want to know more than is mentioned in this video.
DNA is wound around Histones, (like a bead bracelet). Packed into a group of 8 histones known as a nucleosome. Multiple nucleosomes stack on top of each other. The end result is a fiber of chromatin. This chromatin is then looped and further wound and packaged. Think of a rope made of hundreds of strands that is chromatin and the rope is the chromosome.

update: got a 36 on my exam thanks for the help

Thanks a bunch! Sat in a two hour lecture and seminar thinking " You made it a lot more interesting!
Subbed!

Simple, specific, and short 👍🏼thanks for the video

I love your videos! You're really helpful and make things clear every time, thanks a lot!

2:50 I mean its your drawing but really it looks like each ball is a nucleosome and the 8 "histones" you marked as a nucleosomes are just a string of chromatosomes, since like i said each histone you drew looks like a nucleosome. histones don't start arranging in a linear manner, they bind to each other forming a spheric or disk complex called an octamer even before DNA is wrapped on them, when it does, the complex is called a nucleosome

[Oceangirl]

Isn't a nucleosome a histone with a specific length of DNA wrapped around, while those 8 histones packaged belong to solenoid structure bound by SMC proteins?

I like your voice. I don't have to fiddle with my volume cus it's nice n clear n deep! Sexeh! 🙆

your captain is spaking ;dear passengers pls don t forget to fasten your seat belt thank you

Good effort, but you need to check your facts. If you stretch out the human genome, it's between 1.8 to 2 metres long. Maybe you read that it was he atoms lined up and not the molecule. Secondly, you miss the point. If DNA takes up so much space in the cell, how is it a solution to package it by wrapping it around something else. Think why it is useful to package something, rather than just cram it in to a ball.

Dude i like your videos in general. But this was really useless
