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.

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

This is not produced by E.coli in the lactose medium :

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

Which of the following events would occur in 'Lac' operon' of E. coli when the growth medium has high concentration of lactose ?

The operator gene of lac operon is ' turned on ' when lactose molecules bind to

E. coli cell with a mutated Z gene of the lac operon cannot grow in medium containing only lactose as the source of energy because:

E. colicells with a mutated z gene of the lac operon cannot grow in medium containing only lactose as the source of energy because

Given above is the schematic representation of lac operon of E.coli. Explain the functioning of this operon when lactose is provided in the growth medium of the bacteria.
