Polymerases are enzymes that catalyze the DNA or RNA duplication of a template. In the PCR technique, thermostable DNA polymerases are used, such as Taq DNA polymerase, which allows DNA amplification in vitro at a high temperature.
Explains enzyme properties such as thermostability, processivity, fidelity, and specificity in improving PCR results.
