Quizplus · Accepted Answer

Taq polymerase is a heat-stable DNA polymerase derived from the bacterium Thermus aquaticus. It is commonly used in PCR (polymerase chain reaction) to amplify DNA sequences due to its ability to withstand the high temperatures required for denaturation and annealing of DNA strands.
