Question

DNA polymerase isolated from which of the following bacteria is used in PCR method?

Hint:

Taq polymerase from Thermus aquaticus is essential for PCR because of its heat resistance, allowing it to remain active during the high temperatures used in the process.

Answer 1

DNA polymerase used in the Polymerase Chain Reaction (PCR) method is isolated from the bacterium Thermus aquaticus. This bacterium thrives in high-temperature environments, and its polymerase enzyme, known as Taq polymerase, is heat-stable, making it ideal for the repeated heating and cooling cycles required in PCR.
