Question

In E. coli replication the enzyme primase is used to attach a 5 to 10 base ribonucleotide strand complementary to the parental DNA strand. THe RNA strand serves as a starting point for the DNA polymerase that replicates the DNA. If a mutation occurred in the primase gene, which of the following would you expect?

a. Replication would not be affected as the enzyme primase involved with RNA synthesis.
b. Replication would not occur on either the leading or lagging strand
c. Replication would only occur on the leading strand
d. Replication would only occur on the lagging strand

Answer 1

Answer: B

Step-by-step explanation:

Replication would not occur on either the leading or lagging strand.

This is because primase will no longer be able to attach the RNA strand needed for the! DNA replication to start.
