Bacterial Transformation Explained | AP Biology & Biotechnology Applications

This video explains bacterial transformation through Frederick Griffith’s classic experiment. You’ll see how Griffith worked with Streptococcus pneumoniae, why mice lived or died, and how his results revealed that genetic information could be transferred between bacteria. We break down what “transformation” actually means, why the smooth and rough strains behave differently, and how this experiment led scientists to identify DNA as the transforming principle. The video then connects Griffith’s work to modern biotechnology, including genetic engineering, plasmids, and antibiotic resistance. If you’re studying bacterial transformation for AP Biology, college biology, or microbiology, this walkthrough will help you understand the experiment, the logic behind it, and why it still matters today.
