In DNA Replication in E

question 8

Multiple Choice

In DNA replication in E. coli, 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 results would you expect?

• A) Replication would only occur on the leading strand.
• B) Replication would only occur on the lagging strand.
• C) Replication would not occur on either the leading or lagging strand.
• D) Replication would not be affected as the enzyme primase in involved with RNA synthesis.
