How many levels of coiling are there of the DNA to get to the chromosome structure?
I must say, this whole thing seems so unlikely as to be preposterous.
Almost enough to make one believe in an omnipotent, omniscient, omnipresent.... no, not quite.
What are you talking about? Are you detecting some underlying message in that animated movie about flying spaghetti? Um... wait...
I think the movie is fairly accurate, so we should be able to count the levels of coiling.
1. the twist of the DNA helix.
2. wrapping around the histone octamer
3. fiber of nucleosomes (DNA + histone octamers); looks like about 8-10 nucleosomes per turn
4. coiling of that fiber (maybe 10-20 per turn?)
5. coiling of that (#4 and #5 happen pretty quickly together in the video) "this fiber is coiled yet again" (another ~15/turn?)
6. (after a scene break) another coiling, maybe 20/loop?
And that's the chromosome.
So let's check how we're doing for numbers:
200 base pairs / nucleosome X 10 (#3) X 10 (#4) X 20 (#5) X 20 (#6) X 20 (# chromosomes)
= 16 X 10^7 = 1.6 X 10^8
And there are 3 billion base pairs in human DNA = 3 X 10^9
so it's not too far off... order of magnitude or so.
