Question 5 1 pts The enzyme helicase is an important part of the replication machinery, but its use now requires specifically the activity of the following enzyme: Topoisomerase ODNA polymerase Sliding clamp Primase Ligase Question 7 1 pts Much of replication can be studied using extracts from wild type (normal) yeast cells that supply all of the essential components. Compared to wild type extracts, if you use an extract that is missing the sliding clamp AND ligase, what do you...

Question 8 1 pts What is true about the replication forks formed at each replication origin? O At each fork, the replication machine opens up the double helix and uses each DNA strand to make new daughter strands. O Replication forks are X shaped. One replication fork is formed at each replication origin. O The two forks formed at each replication origin move in the same direction, working together to unzip the DNA double helix and replicating the DNA as...

Incorrect Question 3 0/1 pts The replication fork has both leading (continuous) and lagging (discontinuous) synthesis because: a. The origin of replication only allows DNA synthesis to occur in one direction around the chromosome. b. Primase only works on the leading strand c. Helicase is slow in unwinding the double helix so the polymerization moving toward...
