PCR based technique

Polymerase chain reaction (PCR) is a technique used in molecular biology to amplify a segment of DNA. PCR is now a common and often indispensable technique used in clinical and research laboratories for a broad variety of applications such as diagnosis of hereditary disorders, DNA sequencing, gene mutagenesis, analysis of genetic fingerprints in forensic and parentage testing and detection of pathogens in case of diagnosis of infectious diseases.
