How does DNA synthesis along the lagging strand differ from that of the leading strand? a. nucleotides are added to the 5' end instead of the 3' end b. an RNA primer is needed on the lagging strand but not on the leading strand c. ligase is the enzyme that polymerizes DNA on the lagging strand d. okazaki fragments, which each grow 5' to 3', must be joined along the lagging strand

1) Draw a diagram of a bacterial replication fork showing the leading and lagging strand of new DNA and the enzymes responsible for the processes involved. Indicate the 3' and 5' end of each nucleic acid strand. 2) The ends of a linear chromosome cannot be replicated by the normal DNA replication enzymes. Why? How does the eukaryotic cell solve this problem?

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...
