The lac Operon. The lac operon is a cluster of genes that code for a series of enzymes that work together to digest lactose into two monosaccharides: glucose and galactose. Here’s how the expression of these structural genes is controlled. When lactose is absent, the lac operon turns the expression of lactose-digesting enzymes off. A specific small molecule that inactivates the repressor in an operon. Example - Allolactose (green sphere) in diagram. operator.
