Question

Quizplus · Accepted Answer

PCR (polymerase chain reaction) is a widely used technique in molecular biology to amplify a specific piece of DNA. It involves repeatedly heating and cooling a reaction mixture containing DNA template, primers (short DNA sequences that bind to the desired DNA region), nucleotides (building blocks of DNA), and DNA polymerase (an enzyme that can synthesise new DNA strands). PCR can generate millions to billions of copies of the target DNA sequence, making it useful for various applications such as DNA sequencing, cloning, and diagnosis of genetic diseases.
