What is one component that is needed to perform a PCR?
A)primers
B)DNA ligase
C)RNA polymerase
D)deoxynucleoside triphosphates

Question

Quizplus · Accepted Answer

Primers are short nucleotide sequences that anneal to the target DNA template and provide a starting point for DNA polymerase to extend and synthesize new DNA strands. Without primers, PCR cannot occur. B) DNA ligase is not needed for PCR as PCR is a process of amplification of DNA that works through the activity of DNA polymerase. C) RNA polymerase is not used in PCR as it synthesizes RNA and not DNA. D) Deoxynucleoside triphosphates or dNTPs are important, but not the only component needed for PCR. They are the building blocks for the newly synthesized DNA strands, but without primers and DNA polymerase, they cannot be incorporated into a target DNA sequence to produce amplified DNA.
