Question

Lactose plays a dual role in the lac-operon. How?
why is lacoperon said to be under negative regulation ?​

Answer 1

Answer:

Explanation:

When lactose is not available, the lac repressor binds tightly to the operator, preventing transcription by RNA polymerase. However, when lactose is present, the lac repressor loses its ability to bind DNA. It floats off the operator, clearing the way for RNA polymerase to transcribe the operon.
