PCR stand for _________?
Correct answer: A. Polymerase chain reaction
- A. Polymerase chain reaction
- B. Poly carbomyl reaction
- C. Peptide chain reaction
- D. Pentapeptide chain reaction
Explanation
PCR stands for Polymerase Chain Reaction, a laboratory method that repeatedly copies a selected DNA segment using primers, nucleotides and a heat-stable DNA polymerase. Students may select peptide chain reaction because “chain reaction” sounds chemically plausible, but PCR specifically concerns polymerase-driven DNA amplification.
