Section 14.s: regulation of gene expression (summary) the rate of initiation of transcription is related to the presence of rna polymerase and associated proteins at the promoter. the lac operon is a classic, fundamental paradigm demonstrating both positive and negative regulation through allosteric effects on trans factors. The lac operon controls the breakdown of lactose in e. coli bacteria. it consists of three structural genes (lacz, lacy, laca) that are regulated by a single promoter and operator region. in the absence of lactose, a lac repressor binds to the operator, preventing transcription of the structural genes. when lactose is present, it binds to the. The lac operon is a genetic regulatory sequence found in bacteria that codes for the production of enzymes necessary for lactose metabolism. the operon is controlled by a repressor protein, laci, which binds to an operator site on the dna upstream of the genes and prevents their expression. when lactose is present, it binds to laci and.

The lac operon is an example of an inducible operon that is also subject to activation in the absence of glucose (figure 11.34). the lac operon encodes three structural genes necessary to acquire and process the disaccharide lactose from the environment, breaking it down into the simple sugars glucose and galactose. for the lac operon to be.
