Biology 12 | Chapter 10: Polymerase Chain Reaction (PCR) | Lecture 5 (2025-2026) Welcome to Lecture 5 of our 2nd-year Biology series for the 2025-2026 session. In this lecture, we explore the revolutionary technique of Polymerase Chain Reaction (PCR), often called "DNA photocopying."Aligned with the Federal Board (FBISE) and National Book Foundation curriculum, we break down the thermal cycling process and the significance of Taq polymerase in modern biotechnology. In this lecture, you will learn: The three main steps of PCR: Denaturation, Annealing, and Extension. The components required for a PCR reaction. Real-world applications of PCR in forensics and medicine.
