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.

Why does the lac operon shut down some time after the addition of lactose in the medium where E.coli was growing ? Why low level expression of lac operon is always required ?

A low level of expression of lac operon occurs at all the time. Can you explain the logic behind this phenomena.

Read the statements regarding the lac operon and choose the correct option. 1. An inducer regulates the switching on and off of lac operon. 2. Repressor protein dissociates from operator region and prevents RNA polymerase from transcribing the operon. 3. In the presence of lactose, the repressor is activated by interaction with lactose. 4. RNA polymerase has access to the promoter and transcription proceeds only when the repressor is inactivated.

Read the following statements for lac operon: i. Each operon has its specific operator and specific repressor. ii. The y gene codes permease, which increases the permeability of the cell to beta-galactosides. iii. Regulation of lac operon can be visualized as regulation of enzyme synthesis by its substrate. Select the option with the correct statements.
