Which enzyme is required for PCR amplification of DNA?
A) DNA ligase
B) DNA helicase
C) Telomerase
D) DNA polymerase
E) A sliding DNA clamp

Question

Quizplus · Accepted Answer

DNA polymerase is required for PCR amplification of DNA as it is the enzyme responsible for synthesizing new strands of DNA. It extends primers that are annealed to the template DNA, allowing for amplification of the target sequence. DNA ligase, DNA helicase, telomerase, and sliding DNA clamp are not necessary for PCR amplification.
