explain how lac operon function when Inducer is absent

Answers

Answered by Ᏸυէէєɾϝɭყ

When lactose is absent, the lac repressor binds tightly to the operator. Allolactose binds to the lac repressor and makes it change shape so it can no longer bind DNA. Allolactose is an example of an inducer, a small molecule that triggers expression of a gene or operon.
