The effect of the following conditions: when the strain is grown in lactose, the strain is grown without lactose, the lacI gene is deleted, and the lac operator is eliminated. Introduction: Lac operon is required for the transport andÂ metabolismÂ ofÂ lactose. In the absence of glucose, it allows for the effective digestion of lactose. They are used in several bacterial-based selection techniques as a reporter gene. LacÂ operon is regarded to be the first genetic regulatory mechanism and also an example of prokaryoticÂ gene regulation.
