What is Lac Operon Function and Regulation about?

1. The lac operon controls genes for lactose digestion in E. coli. 2. When lactose is present, it binds to the repressor protein which changes shape so it cannot bind to the operator region. This allows RNA polymerase to transcribe the structural genes encoding lactose permease and beta-galactosidase. 3. When no lactose is present, the repressor protein binds to the operator region and blocks RNA polymerase from transcribing the structural genes.
