Polymerase Chain Reaction

Polymerase Chain Reaction (PCR) is a groundbreaking technique that has revolutionized molecular biology and countless scientific fields. Its discovery has made it possible to amplify specific regions of DNA, enabling researchers to study genes and genetic material in unprecedented ways. In this comprehensive guide, we'll delve into the fundamentals of PCR, exploring its applications, benefits, and the career opportunities it presents.

What is Polymerase Chain Reaction (PCR)?

PCR is a technique that allows scientists to make millions to billions of copies of a specific region of DNA. It works by using a heat-resistant DNA polymerase enzyme, which synthesizes new DNA strands complementary to the target DNA sequence. The process is repeated through cycles of heating and cooling, resulting in an exponential amplification of the target DNA.
