Key Concepts: Bacterial DNA polymerase I enzymes are multidomain proteins with separate polymerisation, proofreading and 5â²â3â² exonuclease functions. They perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.
DNA Replication in Bacteria. In general, DNA is replicated by uncoiling of the helix, strand separation by breaking of the hydrogen bonds between the complementary strands, and synthesis of two new strands by complementary base pairing.) . In bacteria, Par proteins function to separate bacterial chromosomes to opposite poles of the cell during cell division. They bind to the origin of replication of the DNA and physically pull or push the chromosomes apart, similar to the mitotic apparatus of eukaryotic cells.
