Answer: DNA polymerase, which is the enzyme involved in DNA replication, is equipped with several mechanisms to prevent errors during DNA replication. During DNA replication, the mispaired bases are replaced by proofreading. Immediately after DNA replication, the remaining mispaired bases are replaced by strand-directed mismatch repair.
