Polymerase chain reaction
Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify a specific DNA sequence. It involves a series of heating and cooling cycles to denature, anneal, and extend the DNA strands, resulting in an exponential increase in the target DNA region.
About
It involves a series of heating and cooling cycles to denature, anneal, and extend the DNA strands, resulting in an exponential increase in the target DNA region. PCR has various applications in research, diagnostics, and forensics, including gene cloning, disease detection, genetic fingerprinting, and DNA sequencing. It was first invented by Kary Mullis in 1983 and has since become a fundamental tool in molecular biology. PCR has revolutionized the field by enabling the study of small DNA samples, detection of rare genetic mutations, and identification of infectious agents. It has significantly impacted various fields and continues to be widely used in diverse biological applications.
