In Which Step Of PCR Taq Polymerase Is Used?
In Which Step Of PCR Taq Polymerase Is Used? “Which of the following steps are catalysed by Taq polymerase in a PCR reaction ?” The final step of PCR is extension, wherein Taq DNA polymerase (isolated from a thermophilic bacterium Thermus aquaticus) synthesises the DNA region between the primers, using dNTPs (denoxynucleoside triphosphates) and Mg2+.
