PCR (Polymerase Chain Reaction) | Grade 12 Biology | Chapter 13 | Topic 3 | FBISE & Punjab Board.

PCR (Polymerase Chain Reaction) is a powerful molecular biology technique used to amplify a specific DNA sequence and produce millions of copies. In this video, we explain the basic principle and three main steps of PCR: Denaturation, Annealing, and Extension in an easy, exam-oriented way. This video is useful for students studying Biotechnology, Molecular Biology, Genetics, Microbiology, and Biology. #PCR #PolymeraseChainReaction #Biotechnology #MolecularBiology #Genetics #DNA #DNATechnology #PCRSteps #Biology #BiologyShorts #StudyShorts
