Assertion :- Lactose is the substrate for the enzyme `beta`-galactosidse & it regulates switching on & off of the operon.
Reson: A very low level of expression of lac operon is always present in cell all the time.

Assertion :- Lactose is the substrate for the enzyme beta -galactosidase & it regulates switching on & off of the operon. Reason: A very low level of expression of lac operon is always present in cell all the time.

Lactose is the substrate for the enzyme beta - galactosidase and it regulates switching on and off of the operon. Hence it is termed as

Assertion (A): Lactose is the substrate for the enzyme beta-galactosidase and it regulates switching on and off of the lac operon. Reason ( R): The lac operon consists of one regulatory gene and three structural genes.

Read the following statements w.r.t. lac operon. Br a. lac-i is the constitutive gene. Br b. lac-y codes for permease to increase permeability of cell to Beta -galactoside. Br c. Lactose is the substrate for the enzyme B- galactosidase and it regulates switching on and off of the operon. br d. Regulation of lac operan can be also visualised as regulation of enzyme synthesis by its substrate.
