PCR requires the use of which enzyme?
A) RNA polymerase
B) DNA ligase
C) helicase
D) DNA polymerase
E) RNA primase

Question

Quizplus · Accepted Answer

PCR (polymerase chain reaction) involves the amplification of DNA and requires the enzyme DNA polymerase to synthesize new strands of DNA. This enzyme is not to be confused with RNA polymerase, which synthesizes RNA. DNA ligase is involved in the sealing of breaks in the sugar-phosphate backbone of DNA, helicase unwinds the DNA double helix, and RNA primase synthesizes RNA primers to initiate DNA replication.
