Questions in DNA Structure and Replication
Page 18 out of 18 Pages
- Are topoisomerase and helicase in the same group of enzymes or do they counteract each other's function?(14554 views)
- Why is the statement "When DNA polymerase III begins synthesis, it covalently links a DNA base to a DNA base." considered a FALSE statement? I thought the DNA polymerase covalently linked the base in a single strand. Could you explain it to me? (5157 views)
- Is a euchromatin a 10nm fiber or a 10nm microfibril? The material that I got says it is a 10nm microfibril. and the TA says fiber and microfibril are not the same thing. (6115 views)
- One of our homework problem asks "Which one of the following scientists helped to demonstrate that DNA, not protein, was the genetic information that viruses inject into bacteria?", and my answer (Hershey/Chase experiment) was correct. However, when I decided to look at the practice exam there is a question very similar to this one where the correct answer is that Avery, McCarty, and MacLeod made the discovery that "DNA and not protein is genetic material" which is exactly how the question is worded on the homework problem. Is this just really misleading or incorrect?(6919 views)
- Could you please check if I have the relative sizes of the following structures arranged correctly:
{(Nuclease=Nucleosome=Kornberg Nucleosome) <(Chromatosome)< (Euchromatin) < (Heterochromatin)}=Chromosome(4883 views)
- 1. Does DNA replication only occur during Mitosis?
2. Does mRNA in Eukaryotes have Ribosome Binding site? Or does the 40S complex bind with 5'cap of mRNA,and it's done?
3. What are the differences between snRNA and snRNP, structurally and functionally? (15050 views)

Why is it not correct to say that "DNA pol I is an RNA dependent, DNA synthesizing enzyme"?

- Can someone explain what Mr. Mehrtens was saying about replicons, ori, and foci. I need help sorting out which ones give way to which ones. (8957 views)
