PCR amplification, or polymerase chain reaction amplification, is a molecular biology technique used to exponentially replicate specific segments of DNA. This process allows scientists to produce millions of copies of a particular DNA sequence from a small initial sample, making it easier to study and analyze genetic material. In the context of thermophilic metabolisms and adaptations, PCR amplification is crucial for studying the unique DNA of extremophiles that thrive in high-temperature environments.
