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?

AThe DNA molecule will supercoil.
BNo replication fork will be formed.
CReplication will occur via RNA polymerase alone.
DNo proofreading of the replicated strands will occur.

Verified Answer :

C.

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

Answer:

b. No replication fork will be formed.

Explanation:

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