Question 7
What problem is caused by the formation of Okazaki fragments and what is the cell’s solution?
They result in excessive twisting of the DNA, which is relieved by Topoisomerase.
They are short, discontinuous stretches of DNA, which must be annealed using Ligase.
They require DNA synthesis to occur in the 3′ to 5′ direction, which is catalyzed by Primase.

Question 8
What kind of enzyme catalyzes polymerization of DNA?
Endonuclease
Polymerase
Primase
Helicase
0.5 points
Question 9
What problem associated with DNA replication is solved by the formation of Okazaki fragments?
DNA replication begins at multiple origins of replication in eukaryotes.
The two strands of DNA are held together by millions of hydrogen bonds, making separation extremely difficult.
DNA must polymerize in the 5′ to 3′ direction on a template.
DNA polymerization requires an existing chain onto which to add new dNTPs.
0.5 points
Question 10
What would you observe in a cell in which DNA helicase was inactivated?
DNA replication would fail due to the inability to separate the two strands of DNA.
DNA replication would fail due to the absence of a primer for DNA polymerization.
DNA replication would begin, but would eventually stall due to the increase in twisting beyond the replication fork.
DNA replication would occur on the leading strand, but not the lagging strand.
