Question

Expand and mention one application of PCR.

Answer 1

The polymerase chain reaction is used to reproduce selected sections of DNA or RNA for analysis. Previously, amplification of DNA involved cloning the segments of interest into vectors for expression in bacteria. The PCR has been elaborated in many ways since its introduction and is now commonly used for a wide variety of applications including genotyping, cloning, mutation detection, microarrays, forensics, and paternity testing.
