15. Central Dogma & Gene Regulation / The Lac Operon / Problem 1

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

A

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

B

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

C

The lac repressor binds to the operator, blocking transcription.

D

Glucose is converted into lactose, activating the lac operon.
