The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.he 3'-5' exonuclease activity of the enzyme allows the incorrect base pair to be excised (this activity is known as proofreading). Following base excision, the polymerase can re-insert the correct base and replication can continue forwards.
Definition. DNA polymerase is a specific class of enzyme found in all living organisms. Its main purpose is to replicate DNA. The enzyme is critical to the transmission of genetic information from generation to generation.ll living organisms have DNA polymerases. A single cell can contain several different polymerases. This includes complex ones which replicate DNA when the cell divides, and simpler ones which help in the day-to-day repair and maintenance of DNA.
