Gene Family: DNA polymerases (POL)

Also known as : "DNA-directed DNA polymerases", "Polymerases, DNA directed"

DNA-directed DNA polymerase: Enzyme that catalyzes DNA synthesis by addition of deoxyribonucleotide units to a DNA chain using DNA as a template. They can also possess exonuclease activity and therefore function in DNA repair. [Source: UniProt. See also GO]
