The fidelity of a DNA polymerase is the result of accurate replication of a desired template. Specifically, this involves multiple taq polymerase proofreading 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. In addition to effective discrimination of correct versus incorrect nucleotide incorporation, some DNA polymerases possess a 3´→5´ exonuclease activity. This activity, known as “proofreading”, is used to excise incorrectly incorporated mononucleotides that are then replaced with the correct nucleotide. High-fidelity PCR utilizes DNA polymerases that couple low misincorporation rates with proofreading activity to give faithful replication of the target DNA of interest. When is fidelity important? Fidelity is important for applications in which the DNA sequence must be correct after amplification. Common examples include cloning/subcloning DNA for protein expression, SNP analysis and next generation sequencing applications. Fidelity is less important for many diagnostic applications where the read-out is simply the presence or absence of a pr

Next Section When describing the structure of the DNA double helix, Watson and Crick (1) wrote, “It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.” Fifty years later, interest error rate in the fidelity of DNA copying mechanisms remains high because the balance between correct and incorrect DNA synthesis is relevant to a great deal of biology. High fidelity DNA synthesis is beneficial for maintaining genetic information over many generations and for avoiding mutations that can initiate and promote human diseases such as cancer and neurodegenerative polymerase error rate diseases. Low fidelity DNA synthesis is beneficial for the evolution of species, for generating diversity leading to increased survival of viruses and microbes when subjected to changing environments, and for the development of a normal immune system. What was not yet appreciated 50 years ago was the large number and amazing diversity of transactions involving DNA synthesis required to faithfully replicate genomes and to stably maintain them in the face of constant challenges from cellular metabolism and the external environment. To perform these tasks, cells harbor multiple DNA polymerases (2, 3), many of which have only been discovered in the past 5 years and whose cellular functions are not fully understood. These polymerases differ in many features including their fidelity. This diversity and the sequence complexity of genomes provide the potential to vary DNA synthesis error rates over a wider range than was appreciated a few years ago.
