Both prokaryotic and eukaryotic cells contain more than one species of DNA polymerase enzymes. Only some of these enzymes actually carry out replication and sometimes they are designated as DNA replicases. The others are involved in subsidiary roles in replication and/or par­ticipate repair synthesis of DNA to replace damaged sequences.
