Paul Andersen explains the major procedures in molecular biology. He starts with a brief description of Taq polymerase extracted from the hot pools of Yellowstone Park. He then uses the analogy of the ransom note to explain each of the processes that are required in genetic engineering. He explains how DNA is cut using restriction enzymes and glued using hydrogen bonds. He explains how gel electrophoresis can be used to sort DNA according to length and how the Polymerase Chain Reaction can be used to copy DNA. He finishes with a brief description of DNA sequencing.

DNA Ligase is what combines broken DNA fragments. I would not say it is just "hydrogen bonding" as that only exists between the bases. The backbone must also be covalently bonded. Good video though.

@bonbonpony 8 жыл бұрын

+Sentient Yeah... The hydrogen bonding can only merge two complementary strands together into one double-helix. But it cannot join two helices together into a longer helix. There has to be something which will make the peptide bond between the 3' and 5' ends.

Shouldn't you include DNA Ligase as the "glue" in addition to hydrogen bonding?

@SS8styles 10 жыл бұрын

from my understanding, ligase seals the nicks along the axis of the double helix between nucleotides, due to the formation of okazaki fragments. Whereas H-bonds actually hold the two strands together, perpendicular to the axis of the double helix. Metaphorically, it might be misleading to think of both as "glue" especially in the context he was discussing, namely, applications of molecular biology. You need to open up the DNA to use it for practical applications such as PCR, so H-bonds are what you need to un-glue to achieve this. On the other hand, I don't think you would need to undo what ligase does b/c there's no practical utility in reproducing okazaki fragments. But don't take my word for it, i aint got no phd.

Nice video, BUT, on min 13:30 he says something wrong, "A is gonna be that little fragment" and points to the top of the gel electrophoresis run, when the smallest fragment would be on the bottom of the gel. though both fragments ended in A, they are very different in length

is it true that we only know a small portion of the full sequence? I heard there is 64 parts but only 24 that are active, if so why doesn't nature use the full sequence? it's almost like d.n.a is waiting to evolve...
