PCR (Polymerase Chain Reaction)

The video begins with a humorous take on the unpredictability of copy machines, leading to an introduction of PCR (Polymerase Chain Reaction) as a biotechnology that copies DNA. It explains the components and steps involved in PCR, including denaturation, annealing, and DNA synthesis. The video highlights PCR's applications, such as DNA fingerprinting and disease diagnosis, with a focus on its role in COVID-19 testing. The conclusion emphasizes PCR's importance and future potential.
