When a bacterial cell is not expressing the genes in the lac operon, this is an example of Transcriptional regulation.

The metabolism-related genes in the Lac operon are present. When glucose is absent and lactose is present, the genes are only expressed.

Lactose acts as an inducer in the lac operon. The regulatory gene is activated when lactose is added to the medium for the bacteria. The repressor protein will become inactive when the inducer binds to it, allowing the operon to be translated. As a result, the lac operon in this instance is negatively regulated.
