Polymerase Chain Reaction (PCR) is a widely used molecular biology technique that allows for the amplification of specific segments of DNA. Developed in 1983 by Kary Mullis, PCR enables researchers to produce millions to billions of copies of a targeted DNA sequence from a small initial sample, making it easier to study and analyze that specific region of DNA.
