Polymerase Chain Reaction (PCR)
Polymerase Chain Reaction (PCR) revolutionized molecular biology by enabling the amplification of specific DNA sequences. Developed in the 1980s by Kary Mullis, this technique has become indispensable in various fields, including diagnostics, forensics, and research. PCR operates through cycles of heating and cooling, replicating DNA exponentially from minute samples. Its applications range from identifying genetic diseases to studying evolutionary relationships. With its sensitivity, speed, and versatility, PCR has profoundly impacted scientific advancements, driving innovations in medicine, agriculture, and biotechnology.
