What is Lac Operon about?
The lac operon in Escherichia coli is a cluster of genes responsible for lactose metabolism, consisting of lacZ, lacY, and lacA, and is regulated by the presence of lactose and glucose. The operon is controlled by a repressor protein (lacI) that inhibits transcription when lactose is absent, and an activator protein (CAP) that enhances transcription when glucose levels are low. This dual regulation allows E. coli to efficiently utilize lactose only when glucose is not available, ensuring energy conservation
