What is the primary purpose of Polymerase Chain Reaction (PCR) in molecular genetics?

• A. PCR amplifies a targeted DNA sequence using primers, DNA polymerase, nucleotides, and thermal cycling to generate millions of copies for analysis.
• B. PCR determines the sequence of a target region using primers and high-throughput sequencing.
• C. PCR transcribes RNA from a DNA template for expression studies.
• D. PCR separates DNA fragments by size during gel electrophoresis.

Answer: (A)
