Abstract

DNA polymerase is a protein that catalyses the polymerization of one strand of DNA, called the primer strand, based on the sequence in another strand, called the template strand. Fidelity in this process refers to the ability of the polymerase to avoid or to correct errors in the newly synthesized strand.
