Which of the following statements explains the importance of enzymes that check for and repair mistakes during DNA replication?

A
The enzymes replace the DNA with RNA
B
The enzymes speed up the rate of RNA synthesis.
C
The enzymes prevent many genetic mutations from being expressed
D
The enzymes remove many recessive gene copies from the nucleus.

Answer:

C!!

Explanation:

The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.

RNA polymerase is an enzyme that aids in the transcription of DNA into RNA during transcript in the nucleus. The enzymes prevent many genetic mutations from being expressed.

Primase is an enzyme that synthesizes short RNA sequences called primers. These primers serve as a starting point for DNA synthesis during replication as the DNA polymerases cannot begin the synthesis of the new strand, they only extend it after primase begins it and primase produces RNA molecules, the enzyme can be said to be a type of RNA polymerase.

Therefore, The statement explains the importance of enzymes that check for and repair mistakes during DNA replication is the enzymes prevent many genetic mutations from being expressed. Thus, the option C is correct.
