inducible operon

Vedclass · Answer

(C) The $Lac$ operon is an example of an inducible operon system.An inducible operon is a genetic regulatory system that is normally switched off (repressed) because a repressor protein binds to the operator.However,it becomes operational (switched on) in the presence of an inducer (such as lactose or allolactose),which binds to the repressor and prevents it from binding to the operator,thereby allowing transcription to proceed.
