NettetThe fidelity of a DNA polymerase is the result of accurate replication of a desired template. Specifically, this involves multiple steps, including the ability to read a template strand, select the appropriate nucleoside triphosphate and insert the correct nucleotide at the 3´ primer terminus, such that Watson-Crick base pairing is maintained. NettetDNA polymerase cannot initiate new strands of nucleic acid synthesis because it can only add a nucleotide onto a pre-existing 3′-OH. Therefore, an 11 to 12 base-pair length of …
