Taq polymerase is useful in PCR primarily because it is heat stable, allowing it to withstand the high temperatures used during the denaturation step of the PCR cycle without denaturing itself. This characteristic enables the enzyme to remain active throughout the cycles of PCR, making it ideal for amplifying DNA.
