B)Only minute amounts are needed for each cycle of PCR.
C)It binds more readily than other polymerases to the primers.
D)It has regions that are complementary to the primers.

Taq polymerase is derived from the bacterium Thermus aquaticus, which can survive and thrive at high temperatures. Taq polymerase itself is also heat stable, allowing it to withstand the repeated heating and cooling cycles of PCR without denaturing. This is important because the polymerase needs to remain active to replicate the DNA during each cycle.
