DNA-directed DNA polymerase

DNA-directed DNA polymerase
DNA-di·rect·ed DNA po·lym·er·ase (dĭ-rekґtəd pə-limґər-ās) [EC] any of the enzymes of the transferase class that catalyze the template-directed, step-by-step addition of deoxyribonucleotides to the 3′ end of an RNA primer or growing DNA chain, using a single-stranded DNA template. The reaction is important in the replication and repair of deoxyribonucleic acids. Called also DNA polymerase.
