Automated PCR machines use a heat stable
A) DNA ligase.
B) helicase.
C) primase.
D) DNA polymerase.
E) amino acid synthetase.

Question

Quizplus · Accepted Answer

Automated PCR machines use a heat stable DNA polymerase, such as Taq polymerase, which can withstand the high temperatures required during the denaturation step of PCR. This polymerase enzyme is responsible for amplifying the target DNA sequence. Other options listed (ligase, helicase, primase, amino acid synthetase) are not involved in the PCR amplification process.
