How does dna polymerase prevent mutations? a. it checks amino acids during protein synthesis. b. it uses translation and transcription. c. it checks dna for errors during replication. d. it creates extra copies of each dna.

(C). It checks DNA for errors during replication.

Explanation:

DNA polymerase is an enzyme that synthesizes the daughter DNA strands from parent DNA molecule at the time of DNA replication. It has both polymerase and proofreading activity.

The proofreading activity of DNA polymerase is responsible for the prevention of mutations that arise during replication.

Once a DNA polymerase detects an incorrect nucleotide base in growing chain, it stops replication and removes the incorrect nucleotide by exonuclease activity and prevents mutations.

Thus, the correct answer is option (C).
