Polymerase enzyme function
The main function of DNA polymerase is to synthesize DNA from deoxyribonucleotides, the building blocks of DNA. The DNA copies are created by the pairing of nucleotides to bases present on each strand of the original DNA molecule. This pairing always occurs in specific combinations, with cytosine along with guanine, and thymine along with adenine, forming two sepa… WebSep 29, 2024 · The chromatin-associated enzyme poly(ADP-ribose) polymerase (ADPRT; EC 2.4.2.30) uses NAD as substrate to catalyze both the covalent transfer of ADP-ribose to a variety of nuclear protein acceptors and subsequently the transfer of an additional 60 to 80 ADP-ribose units to the initial moiety.Nuclear proteins that become predominantly …
