5. a) Draw a diagram of a replication bubble that shows two replication forks (mark them clearly) and indicate all of the following for one of the replication forks: newly synthesized leading and lagging strands (label 5' and 3 ends), RNA primers, DNA polymerase, helicase, and gyrase (topoisomerase). b) There are three enzymes in the list in part a. What function(s) do each of these play in DNA replication? You can answer this here, or include it on your diagram....

a) Suppose you label dividing cells with ^32P. In which DNA molecules will the radioactivity be incorporated if you were to look during metaphase? b) Suppose you are examining the above cells after replication. In which DNA molecules will the radioactivity be present? In one picture, draw a schematic indicating how DNA is synthesized bi-directionally. The schematic should indicate which are the lagging strands, which are the leading strands, where the RNA primers are, and the 3' and 5' orientation...

For the next group of questions consider a diploid cell from a eukaryotic organism with a total of ten chromosomes. After one round of the cell cycle is complete you observe a total of four daughter cells. During this cell division occurred and the resulting daughter cells are. mitosis; haploid with ten total chromosomes each mitosis; diploid with five total chromosomes each meiosis; diploid with ten total chromosomes each meiosis; haploid with five total chromosomes each Before the cell divided,...

Please answer all
Question 1 (0.5 points) Why is there a lagging strand and a leading strand during replication? O Because the helicase unwinds the dna in only one direction. Because DNA polymerase can only add nucleotides to the 3'end of a chain of nucleotides and replication proceeds in both directions. b) c) Because a primer must be laid down first. because DNA polymerase lacks proofreading ability. Save Question 2 (0.5 points) What step(s) in polymerase chain reaction are necessary...
