Function of primase during dna replication
WebApr 6, 2024 · The initiation of Okazaki fragment synthesis during cellular DNA replication is a crucial step for lagging strand synthesis, which is carried out by the primase … Web2.5 (4 reviews) DNA replication is the process of producing two identical copies of DNA, in which each template for the synthesis of a new complementary daughter strand. The central enzyme involved is DNA polymerase, which catalyzes the joining of deoyribonucleoside 5'-triphosphates (dNTPs) to form the growing DNA chain.
