What is Lac Operon Overview for Class 12 about?

The operon model, proposed by Francois Jacob and Jacques Monod in 1961, describes gene regulation in prokaryotes through structural and regulatory genes. The lac operon is an example of an inducible operon that allows E. coli to metabolize lactose in the absence of glucose, involving structural genes like Lac Z, Lac Y, and Lac A, along with a repressor and promoter. This model illustrates the mechanisms of gene expression and regulation through activators and repressors.
