When an incorrect base pair is recognized, DNA polymerase moves backwards by one base pair of DNA. Error correction is a property of some, but not all DNA polymerases. This process corrects mistakes in newly synthesized DNA.
A primer is a strand of nucleic acid that serves as a starting point for DNA replication. PCR is made quick and efficient by having DNA primers already in solution. CSET Science Subtest II Life Sciences (217): Practice & Study Guide Although DNA replication in vivo requires several enzymes and proteins, PCR is accomplished with only one enzyme, DNA polymerase I, in addition to primers, dNTPs, and a DNA template.A primer is required for a PCR reaction primarily because primase is not used in PCR.
rRNA: Sequence, Function & Synthesis This pairing always occurs in specific combinations, with cytosine along with guanine, and thymine along with adenine, forming two separate pairs, respectively.

What is Annealing? Bacterial Transformation: Definition, Steps & Analysis There is a dramatic increase in processivity at the Based on sequence homology, DNA polymerases can be further subdivided into seven different families: A, B, C, D, X, Y, and RT.
