http://www.FreeScienceLectures.com First the DNA Wrapping is animated. The wrapping allows 6 feet of the long DNA molecule to be densely packed into the tiny nucleus of every cell. The process starts when DNA is wrapped around special protein molecules called histones. The combined loop of DNA and protein is called a nuclei zone. Next the nuclei zones are packed into a thread. The end result is fiber known as chromatin. This fiber is looped and coiled yet again leading to the familiar shapes known as chromosomes which can be seen in the nucleus of dividing cells. Chromosomes are not always present - they form around the time cells divide when the two copies of the cell's DNA need to be separated. Using computer animation based on molecular research we are now able to see how DNA is actually copied in living cells. An assembly line of amazing biochemical machines are pulling apart the DNA double helix and cranking out a copy of each strand.

Jul 10, 2008 - FAIL, again. I was referring to THIS video, which only has thirty comments and roughly 35,000 views, and is thus obscure-- not the incredibly stupid documentary you brought up earlier. Every time you post, you just embarrass yourself further. You really have no authority to criticize somebody else's prose.

Jul 10, 2008 - If i don't have the authority to criticize someone else's prose, then you DEFINITELY don't have the authority to criticize one intellectual level because of their posting history.
MattressGallery Says:
Jul 10, 2008 - No, it doesn't work that way. People who have a history of writing ignorant, moronic, or terrible prose should not critique the writing style of others. I, however, do reserve the right to critique your intellectual level, because I have an extensive knowledge of microbiology, and because you repeatedly demonstrate your ignorance of simple logical concepts. You can criticize me however you want. Just don't expect people to think highly of you.

Jul 10, 2008 - There is a clear difference between propriety and legality. It is legal for you to say anything you want on youtube, but when conversing with educated individuals, it is not proper for you to spew ignorant garbage about evolution or "holographic universes".

Jul 10, 2008 - "im not sure if im going to flamed for this comment butwho really gives a fuck. i just read all the other comments visible on the page right now and honestly. this has really nothing to do with the video and to me it seems like everyone is just ranting about god and taking this opportunity to make themselves look smarter or more religiously informed. its all quite pointless." evn tho this is frm anthr vid, i red ths cmmnt nd i thnk itz a sign frm god. Im not gonna argue with ppl n e more.

Jul 10, 2008 - Bleev wut u want son. Just know that you are decieved. Look up the two sermons by ivor myers calld "The black whole" and "Jury selection" U will then see y satan has thuroughly decieved you. Good night. im out, son
MattressGallery Says:
Jul 10, 2008 - There you go. JRocka114 has revealed himself to be a lunatic, a credulous fool, an illiterate troglodyte, and a rambling theistard, all within the span of ten comments. "i red ths cmmnt nd i think itz a sign from god. im not gonna argue with ppl n e more." Good riddance, I say.
MattressGallery Says:
Jul 10, 2008 - *Exactly what I'm talking about. A lunatic. The only thing "Satanic" about this argument is your scientific ignorance.. Only an supernatural demon from the depths of Hades could conjure up such delicious stupidity.

Jul 10, 2008 - "What a fag" That says enough about your character. I have nothing more to say to you.

Jul 13, 2008 - Very interesting video. What are those green thingies in DNA copying process?
lcfr2004 Says:
Jul 14, 2008 - This is great stuff and it is very helpful for me right now because I have a microbiology final tomorrow where I have to explain DNA replication in detail. Thanks FSL and keep up the good work. :)
jfl187 Says:
Sep 23, 2008 - that last part blew my mind. is this really how dna is replicated? somones seen it? really look like that? or is it just an animation to get the idea of how it works?

Oct 27, 2008 - This is absolutely incredible
wonderlasting Says:
Nov 12, 2008 - Thank you so much for this amazing video. I'm a big visual learner and this helped out a great deal.
covidiu Says:
Nov 17, 2008 - That DNA replication thing is amazing. It looks and works like a robot, but it's just a bunch of proteins...
inthefade Says:
Nov 17, 2008 - This is absolutely incredible. I've been looking for a video like this for a while, as I had only stumbled upon them in the context of creationist videos.

Nov 27, 2008 - yes.. it scared the hell out of me but fascinated me incredibly at the same time
dinmagic Says:
Nov 29, 2008 - so complex

Nov 30, 2008 - i have information from a well respected person inside the nanotechnology and molecular science community that this will lead to immortality :P

Jul 10, 2008 - "I'm not the one who chimped out on the comments section of an obscure video" You called the video obscure. Obscure means something vague or unclear. what i was asking is how could someone of such high intellect not understand this vid, according to the meanig of the word obscure? it looks like YOUR reading comprehension is limited. AND STOP USING METAPHORS!!! lol
