Question

In the presence of high levels of glucose and absence of lactose, how is the lac operon in E. coli regulated?

Accepted Answer

The lac repressor binds to the operator, blocking transcription.

Answer

The lac repressor is inactivated, leading to high levels of transcription.

Answer

High levels of cAMP activate CAP, which then enhances transcription.

Answer

Glucose is converted into lactose, activating the lac operon.
