The Polymerase Chain Reaction (PCR) copies a single strand of DNA by first attaching primers. These are short fragments of synthetic DNA, designed to be complimentary to the original strand.

The experiments outlined in the study provide students with hands-on practice assembling master mixes for PCR, using pipettes, and performing the various steps involved in PCR amplification.

PCR is a common laboratory technique used to amplify or copy small segments of genetic material, for example in DNA fingerprinting, diagnosing genetic disorders or detecting bacteria or viruses ...
