Our Grade 11 IBDP Biology students are currently diving deep into the cutting-edge world of biotechnology, mastering the intricate processes of PCR (Polymerase Chain Reaction) and Gel Electrophoresis. By simulating how scientists amplify specific DNA sequences and separate fragments by size, students are gaining a sophisticated understanding of the molecular foundations of life. These techniques are the backbone of modern forensic science, allowing investigators to construct precise DNA profiles from minute biological samples. This unit offers a rigorous bridge between theoretical biochemistry and its real-world applications in justice and medicine. It is inspiring to watch our young scientists develop the technical precision and analytical skills required to navigate this high-stakes field.
