Super Coiling of DNA

Before cell division (both mitosis AND meiosis) the blueprints(DNA) are coiled...and coiled...and coiled some more for safer transport when theyare pushed and shoved around by spindle fibers. This happens in prophase of mitosis and Prophase I and Prophase II of meiosis.

What is the song?

[picardposer]

@joycebaby76 the music is from Kill Bill when bill stumbles into the yard

this is the most epic video i have ever seen in my life

[picardposer]

you made be blush:most...epic...ever. Hi praise and sincere thanks back at you!

Just wondering, where do histones come in? Were they the little balls that came around 0:21?

[picardposer]

The spheres are the histones. Think of a spool with DNA as thread. Although recent research indicates the histones may play role(s) in gene regulation.

i love the dramatization with the song, especially towards the end. it made the chromosome feel like a giant cactus. idk im weird.

[Armondahad]

which song is this?? i looked through the soundtracks and couldn't find it... nice vid btw

@LSDelusions Professor Bermingham at UVM just played this today in class, it received an ovation. She pumped up the music too!

[LSDelusions]

If only they showed this at school and university... Every kid and I mean EVERY kid, would wanna end up being a biologist (and cry afterwords but this another aspect :P)

[SuperLLL]

very cool video...but isn't this just the regular coiling of the double helix around the histones?Isn't supercoiling involving DNA gyrase or topoisomerase II?

@ScienceFan1859 that's right 2m for diploids and 1m for haploid cells.

[zenithar6666]

just another result of our beloved random mutations and natural selction, give me afucking break



[ScienceFan1859]

@SteU4IA if you're talking human cells, it's 2 m...even more amazing!

[SteU4IA]

AND THAT! Ladies and gentlemen...is how our cells can pack in 1m of dna

[alliieexoxo7]

So cool

[permatroll]

@picardposer can you PLEASE tell me the source of this animation? It's pretty awesome! :D
