Document Summary
Study questions for the lectures 5-7: thinking question re dna/rna structure: certain chemical agents acting on dna could convert cytosine to uracil through the process of deamination (chopping off the amino group). This mutation is routinely repaired by the existing repair mechanism (uracil is removed and it gets replaced by cytosine). , it is initially difficult for sequences to find their complements during sequence), whereas eukaryotic (calf) genome consist of 3 classes of dna sequences: unique (single copy), moderately repetitive, and highly repetitive dna sequences. In e. coli renaturation; however, once they are found, there is fast re-association (zippering) In calves repetitive sequences, then middle renaturation of the moderately repetitive sequences, and then slow renaturation of the unique sequences. , there is fast renaturation of the highly: the difference in renaturation patterns of e. coli and calf genome give them 2 different cot curves (e. coli.
