The ATP video inspired me to find this. I remembered watching it in Bio a few years back.

Can some smart sifter give the "voiceover?" I have no idea what's happening. Molecular Biology isn't my strong point.

Well, that is cool. It's making a chromosome... but that's as much as I know. it's insane how fast the procress actually is.

It's showing a computer animated representation of chromatin (DNA) condensing in order for a cell to replicate. At the beginning of the process we see a simple double-strand of DNA. The little critters that attach to it are called histones. The DNA coils around these and then the histones link together to further coil the DNA. After that the details get fuzzy for me, I had medical biochem and genetics last year.

Interestingly, if you were to stretch out the DNA molecule in a human cell into one continuous strand it would be about 3 meters long, depending on whose research you look at.

Amazing.

If you add up all the DNA in all the cells in the size of an average human you could go from the earth to the sun almost 70 times!
