Polymerase Chain Reaction (PCR) is a revolutionary molecular biology technique used to amplify specific DNA sequences. Developed by Kary Mullis in 1983, PCR involves a cyclic process comprising denaturation, annealing, and extension phases, facilitated by thermal cycling. The core enzyme used in PCR is DNA polymerase, typically derived from the thermophilic bacterium Thermus aquaticus (Taq polymerase). Taq polymerase's unique feature is its ability to withstand high temperatures during denaturation, unlike typical enzymes which would denature under such conditions. In vivo, DNA polymerase's primary function is to synthesize DNA strands by adding nucleotides to a primer complementary to the target DNA. PCR's ability to rapidly amplify DNA has profoundly impacted microbiology by enabling quick detection and identification of pathogenic microbes, facilitating genetic studies, and advancing diagnostics in infectious diseases (Mullis & Faloona, 1987; Saiki et al., 1985). This method has enhanced microbial research efficiency, sensitivity, and scope, transforming diagnostic microbiology (Gürtler et al., 2014).
