Replication The main function of the DNA polymerase is to synthesize DNA by the process of replication. It is an important process to maintain and transfer genetic information from one generation to another. DNA polymerase works in pairs, replicating two strands of DNA in tandem. They add … See more The main function of DNA polymerases is to duplicate the DNA content of a cell during cell division. They do so by adding nucleotides at 3’-OH … See more The structure of most of the DNA polymerases resembles a hand, which is holding active sites. The active site of the enzyme has two parts. At the insertion site, nucleotides are added. After adding, the newly formed … See more The reaction is phosphoryl group transfer.
