Question

dna polymerase uses what kind of enzymatic activity in the process of proofreading? check all that apply 5 to 3 exonuclease activity to remove the mismatched bases 3 to 5 exonuclease activity to remove the mismatched bases 5 to 3 polymerase activity to replace the excised bases 3 to 5 polymerase activity to replace the excised bases

Explanation:

DNA polymerase uses 3' to 5' exonuclease activity to remove mismatched bases during proof - reading. After the mismatched base is removed, it uses 5' to 3' polymerase activity to replace the excised bases.

Answer:

B. 3' to 5' exonuclease activity to remove the mismatched bases
C. 5' to 3' polymerase activity to replace the excised bases
