AP Biology Transformation Lab: pGLO & Efficiency 🧫

Learn how to design and analyze bacterial transformation labs for AP Biology Unit 6. This review covers transformation protocols, plasmid function, antibiotic resistance markers, and how to calculate transformation efficiency for your exam.

Bacterial transformation is a critical lab skill that connects to gene expression and genetic engineering. You'll walk through the pGLO plasmid experiment, understand why selection markers matter, and learn how to interpret colony counts. This video also covers the central dogma, transcription factors, and prokaryotic gene regulation to give you the full context behind transformation.
