What is DNA polymerase able to do so that mutations are avoided during replication?
1 answer
DNA polymerase is able to proofread and correct errors during replication by having an exonuclease activity that allows it to remove mismatched bases. This helps prevent mutations by ensuring that the new DNA strand is accurately copied from the template strand. Additionally, DNA polymerase has a high fidelity, meaning it has a low error rate in replicating DNA.
