Practicing Success
During expression of lac operon, RNA polymerase binds to which one of the following region ? |
Operator region . Inducer . Promoter region . Structural genes . |
Promoter region . |
In the presence of an inducer, such as lactose or allolactose, the repressor is inactivated by interaction with the inducer. This allows RNA polymerase access to the promoter and transcription proceeds . Lac Operon |
