Lac operon
Lactose regulating gene and their control elements
Genes that regulate the breakdown of the disaccharide lactose plus the regulatory sequences near them
The regulator gene, CAP-binding site, promoter, operator, 5' UTR coding region, ß-galactosidase gene, galactoside permease gene, and transacetylase gene
Lactose is present.
Repressor protein is bound to the operator.
Allolactose binds to the promoter.
All of the above.
