WebDNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add. This process is called proofreading.If the polymerase detects that a wrong (incorrectly paired) nucleotide has been added, it will remove and replace the nucleotide right away, before … WebThe level of fidelity can also be expressed in relative terms, often using Taq DNA polymerase as the relative standard (Table 1). Note that while single base substitution errors are the easiest to assess, polymerases are also capable of insertion/ deletion errors that can lead to frameshift mutations, a highly deleterious type of error.
