DNA polymerase - Wikipedia
WebA DNA polymerase is a member of a family of enzymes that catalyze the synthesis of DNA molecules from nucleoside triphosphates, the molecular precursors of DNA. These enzymes are essential for DNA replication and usually work in groups to create two identical DNA duplexes from a single original DNA duplex.
DNA Polymerase: Structure, Types and Functions - BYJU'S
WebDNA polymerase duplicates the cellular DNA content every time a cell divides so that there is an equal distribution of DNA to the daughter cells. The three main functions of DNA polymerase are: 5’→3’ polymerisation – it is required for replication and to add nucleotides at the 3’-OH group of the growing DNA strand and filling the gaps.

WebMay 24, 2020 · DNA polymerase has varying roles in the mechanisms of DNA synthesis, repair, and replication. DNA polymerase is categorized into seven different families in eukaryotes, viruses, yeasts, and bacteria. These seven families are A, B, C, D, X, Y, and reverse transcriptase (RT).
DNA Polymerase – Definition, Types, Structure, and Functions
WebNov 7, 2023 · The primary function of the DNA polymerase is to synthesize new DNA strands through replication. It helps transfer genetic information from the parent to the offspring. They work in pairs, in tandem, for the two strands. DNA polymerase catalyzes the synthesis of complementary DNA strands to the template strands.
Molecular mechanism of DNA replication - Khan Academy
WebOne of the key molecules in DNA replication is the enzyme DNA polymerase. DNA polymerases are responsible for synthesizing DNA: they add nucleotides one by one to the growing DNA chain, incorporating only those that are complementary to the template.
