WebA) The lac operon is a gene regulatory system found in bacteria that controls the use of lactose as an energy source. It is composed of 3 structural genes (lacZ, lacY, and lacA), a promoter, and an operator. When lactose is present, it binds to a protein called the lac repressor, which prevents the expression of the structural genes.
