The Polymerase Chain Reaction is Used to Duplicate Small Sections

Question

The polymerase chain reaction is used to duplicate small sections of
A) DNA.
B) RNA.
C) proteins.
D) lipids.
E) lipopolysaccharides.

Accepted Answer

The polymerase chain reaction (PCR) is a commonly used molecular biology technique to amplify or duplicate specific sections of DNA. PCR requires a DNA template, primers, nucleotides, and a DNA polymerase enzyme to synthesize new DNA strands. RNA, proteins, lipids, and lipopolysaccharides are not duplicated using PCR.
