Lac Operon 🧬 : Molecular Biology • Structure • Repression & Derepression • Biochemistry • Dr. Rajesh Tanwar

Lac Operon is one of the most important concepts in Molecular Biology that explains how bacteria regulate gene expression according to environmental conditions. In this lecture, we will understand the structure of the Lac Operon, including the Regulatory Gene, Promoter, Operator, and Structural Genes (lacZ, lacY, lacA). We will also discuss the role of the Repressor Protein, Inducer (Lactose/Allolactose), and the difference between Negative and Positive Regulation. This topic is highly important for MBBS, NEET PG, INICET, FMGE, and university examinations. Watch till the end to master the complete mechanism of gene regulation in prokaryotes in a simple and easy Highlish language.
