Detailed explanation-1: –a type of enzyme that synthesizes new strands of DNA complementary to the target sequence. The first and most commonly used of these enzymes isTaqDNA polymerase (fromThermis aquaticus), whereasPfuDNA polymerase (fromPyrococcus furiosus) is used widely because of its higher fidelity when copying DNA.

Detailed explanation-2: -DNA polymerase (DNAP) is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules.

Detailed explanation-3: -Polymerase does not create a novel DNA strand from scratch. Instead it synthesizes a new strand of DNA based on the template of two existing DNA strands. It does this with the help of another enzyme, called helicase, which unwinds the double helix structure of the DNA molecule into two single DNA strands.
