Question

A mutation in a gene causes an alteration in the structure of helicase. Which of the following would you expect as a result of this mutation?

a. The DNA molecule will supercoil.
b. No replication fork will be formed.
c. Replication will occur via RNA polymerase alone.
d. No proofreading of the replicated strands will occur.

Answer 1

b. No replication fork will be formed.

Step-by-step explanation:

Helicase unwinds the DNA to begin with. Without it, the replication fork cannot be formed.

Answer 2

C.

Helicase helps in DNA replication and if its structure is altered, it will not be able to carry out this task.
