Polymerase - Wikipedia
WEBIn biochemistry, a polymerase is an enzyme ( EC 2.7.7.6/7/19/48/49) that synthesizes long chains of polymers or nucleic acids. DNA polymerase and RNA polymerase are used to assemble DNA and RNA molecules, respectively, by copying a DNA template strand using base-pairing interactions or RNA by half ladder replication.

WEBMay 24, 2020 · DNA polymerase is an important enzyme group involved in DNA synthesis, repair, and replication; these enzymes are found in all living organisms. Originally discovered during research into Escherichia coli bacteria, we now know of multiple varieties with similar structures but different functions.
Polymerase chain reaction (PCR) (article) | Khan Academy
WEBKey points: Polymerase chain reaction, or PCR, is a technique to make many copies of a specific DNA region in vitro (in a test tube rather than an organism). PCR relies on a thermostable DNA polymerase, Taq polymerase, and requires DNA primers designed specifically for the DNA region of interest. In PCR, the reaction is repeatedly cycled ...
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. During this process, DNA polymerase ...

WEBDNA Polymerases: Structural Diversity and Common Mechanisms*. Possibly the earliest enzymatic activity to appear in evolution was that of the polynucleotide polymerases, the ability to replicate the genome accurately being a prerequisite for evolution itself.
Anatomy of a Polymerase - How Function and Structure are Related
WEBDNA polymerases ensure accurate replication using a series of molecular checkpoints, at the site of nucleotide incorporation and beyond (1). During nucleotide addition, the correct incoming nucleotide is positioned for a productive alignment of catalytic groups, ensuring efficient incorporation.
