NEET 2021 Biology Paper

PCR is Polymerase Chain Reaction.
It is used for making multiple copies of the gene.
Hence PCR is used for
• Gene amplification.
• PCR-based assays have been developed that detect the presence of gene sequences of the infectious agents.
• It is also used in detecting mutations.
• Protein is not the target of PCR. Hence, plays no role in its purification.
