- There are 6 parts to this question: This is a follow up to the prior question regarding the replication of the DNA strand below. The DNA strand is here for your reference and you do not need to do anything with or to it. TC GATATCGG AGCTATAGCC c) what enzyme separated the parental DNA template strands, d) what bonds were broken? e) what enzyme replicates DNA f) before DNA can be replicated/copied, what must be laid down to allow the enzyme in "e" to replicated the DNA (be specific)? g) our DNA is replicated in many "pieces", what enzyme connects these many "pieces" into one continuous DNA strand that becomes the sister chromatid? h) during what specific phase of the cell cycle does this DNA replication process occur? (This should be a review question from last topics we covered).Jerome Vinograd found that when circular DNA from apolyoma virus is subjected to cesium chloride gradientcentrifugation, it separates into two distinct bands, oneconsisting of supercoiled DNA and the other of relaxedDNA. Explain how you would identify each band.Is it biologically possible for DNA to undergo replication in vivo, without the lagging and the leading strands? In PCR, we also start with an antiparallel strand of DNA. Does this also mean that replication is semi-discontinuous in in vitro replication?
