Preferred Label : lac operon;
MeSH definition : The genetic unit consisting of three structural genes, an operator and a regulatory
gene. The regulatory gene controls the synthesis of the three structural genes: BETA-GALACTOSIDASE
and beta-galactoside permease (involved with the metabolism of lactose), and beta-thiogalactoside
acetyltransferase.;
