WebProofreading by DNA polymerase corrects errors during replication. Some errors are not corrected during replication, but are instead corrected after replication is completed; this type of repair is known as mismatch repair ( [link] ). The enzymes recognize the incorrectly added nucleotide and excise it; this is then replaced by the correct base.
