DNA Replication 1

"Using computer animation based on molecular research, we are able to picture how DNA is replicated in living cells. You are looking at an assembly line of amazing miniature biochemical machines that are pulling apart the DNA double helix and cranking out a copy of each strand. The DNA to be copied enters the production line from bottom left. The whirling blue molecular machine is called a helicase. It spins the DNA as fast as a jet engine as it unwinds the double helix into two strands. One strand is copied continuously and can be seen spooling off to the right. Things are not so simple for the other strand because it must be copied backwards. It is drawn out repeatedly in loops, and copied one section at a time. The end result is two new DNA molecules."

i enjoyed this vid

[SkylarkWalker]

i sure glade my cells know how to do this, cuz i sure as hell dont!

@MrTatzer You know I'm joking. But, yeah, I don't know much about it. I wish I did. I will get more into it in a few month and probably in the future too. And I will try to learn a little in the meantime. :)

@MrFreakHeavy So you don't know how this system came into existence?

[MrFreakHeavy]

@MrTatzer When you get Mew to Level 1200, it evolves to this awesomeness. ;)

This when you think that Magic and Science fiction is HIGLY over-rated. And reality WAY WAY under-rated. When reallity if FAR MORE AMAZING! :D
