The 3'5' exonuclease activities of DNA polymerases read nascent strands as they are synthesized,removing any mispaired nucleotides at the 3¢ termini of primer strands.This action is known as:

Question

Quizplus · Accepted Answer

The 3'→5' exonuclease activity of DNA polymerases is involved in proofreading, which helps to remove mispaired nucleotides at the 3' termini of primer strands. This helps to improve the accuracy of DNA replication. Choices A, C, D, and E are not correct terms for this process.
