Question

The type of ATPases associated with the integral binding of ATP as part of the transport process and possessing a conserved domain for the binding of ATP is the V type P type F type ABC type no correct choice listed How many replication forks are formed when an origin of replication is opened? 1 2 3 4 Either C or D and depends whether it is a eukaryotic or prokaryotic cell. What part of the DNA replication process would be most directly affected if a strain of bacteria lacking primase were used to make the cell extracts? Initiation of DNA synthesis Okazaki fragment synthesis leading-strand elongation lagging-strand completion none of above would be affected. You have discovered an "Exo^-" mutant form of DNA polymerase in which the 3' -to-5' exonuclease function has been destroyed but the ability to join nucleotides together is unchanged. Which of the following properties do you expect the mutant polymerase to have? It will polymerize in both the 5'-to-3' direction and the 3'-to-5' direction. It will polymerize more slowly than the normal Exo^+ polymerase. It will be more likely to generate mismatched base pairs. No correct Choice listed.
