  • @deanjean71 I love the delete tab. 

  • this video helps me to understand the RECOMBINANT DNA now im ready for the test tommorow :)

  • Also, many organism's dont have DNA at all but RNA (Bacteria, Virus's)

  • Wow, this video came on a promo DVD/CD with a Compaq computer I bought back in 1995. Never thought I'd see it again. How old is this animation?!

  • DNA for kindergarten

  • youd have to be fuckign retarded not to know this shit.

  • hmmm thanxs it helped me understand my lessons a bit....!

  • OOOOh, do the ARN'T to scale... got it!

  • what is the "tape" in gene splicing that is used

  • @Sebastianxbox360 DNA polymerase III would catalyze phosphodiester bonds between nucleotides that are next to each other on the backbone. Also hydrogen bonds form without an enzyme, between nucleotides that are across from each other, holding the 2 strands together. I think thats how it goes.

  • @DarthHater100 Dna ligase would also repair any breaks with a phosphodiester bond.

  • in a way this was not hard to find but because i am a fucking retard it took forever

  • Are you sure recombinant insulin isn't human insulin? Last time I checked the two separate recombinant plasmids do code for the exact copies of alpha and beta chains that also compose "natural" insulin. Let me explain it in layman terms, two strings compose insulin's basic structure, in the body these aren't as easily differentiated. Recombinant technology makes each string in separate cultivation reactions and then puts both string together to form, guess what, the same "natural" protein.

  • "Every organism has millions of strands of DNA in each cell"

    Nope.

    Most bacteria have ONE circular strand.

    Most human cells have

    23 chromosomes X 2 copies=46 strands of DNA

    Plus several thousand copies of very small circular mitochondrial DNA.

  • thanks for the correction, always liked it when people put out the right info

  • It says "EVERY ORGANISM HAS MILLIONS OF STRANDS". Not each CELL has millions of strands.

  • "in each cell".

    It would still be wrong. Many organisms (bacteria, yeast) have only one cell.

  • @grillapineapple yeah definite FAIL!!

  • Comment removed

  • Is this how they made those flourescant mice? Interesting...

  • thats my DNA

  • the new one is not the same not at all the same if you can see

  • wow that acually did it... they made a cow-human...

  • I don't understand this shit because I'm stupid. I can't wait to be done with this chapter in my micro textbook. yuck.

  • i wish i was a recominated dna freakXD

  • prolly already are...

  • Not bad.
