What is the purpose of Taq polymerase in a PCR reaction?

Question

Quizplus · Accepted Answer

Taq polymerase is a type of DNA polymerase that is optimal for use in PCR reactions because it can withstand the high temperatures needed for DNA denaturation and extension (around 94°C). Its main purpose in the reaction is to synthesize new strands of DNA using the primers as a template. While Taq polymerase is involved in all aspects of the PCR reaction (denaturation, annealing, synthesis), its function as a polymerase is the most important.
