How would lac operon operate in E. coli growing in a culture medium where lactose is present as source of sugar ?

(a) Explain the role of regulatory gene, operator and structural genes in lac operon when E. Coli is growing in a culture medium with the sources of energy as lactose.

(a) Explain the role of regulatory gene, operator and structural genes in lac operon when E. Coli is growing in a culture medium with the sources of energy as lactose.

Explain how lac operon operates in E.coli in the absence of an inducer.

Describe lac - operon concept in E- coli.

How is lac operon ‘switched on’ in an E. coli cell?

Lac operon will not remain active if culture medium containes :-

Where is the lactose operon present in E.coli genome?

Escherichia coli with mutated z gene of lac operon cannot grow in medium containing only lactose as the source of energy because
