Polymerase chain reaction

Polymerase chain reaction (PCR) is a molecular biology technique used to amplify specific DNA sequences, enabling the generation of millions of copies from a small initial sample. This method is crucial in clinical practice for diagnosing infectious diseases, genetic disorders, and in forensic science, as it allows for rapid and sensitive detection of pathogens or genetic mutations. A key application of PCR is in the detection of SARS-CoV-2, the virus responsible for COVID-19.
