Prokaryotic DNA replication is THETA replication with one origin and five DNA polymerases. DNA Polymerase III is the main replicating enzyme with a high processivity and a fast 5'-3' polymerase and 3'-5' exonuclease. DNA Polymerase I has a low processivity and a slow 5'-3' polymerase and 3'-5' exonuclease. DNA Polymerase I, II, IV, and V are responsible for DNA repair in prokaryotes.
