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.

Which of the statements given below about the Champaran Satyagraha is/are correct? 1. It was related to Indigo plantations. 2. It started because the European planters oppressed the Zamindars. Select the correct answer using the code given below:

The lac operon consists of a regulation gene and three structural gene. The lactose acts as inducer. In the presence of an Inducer such as lactose, the repressor is in inactivated during the interaction. This allows RNA polymerase access to the promoter and transcription proceeds. The repressor is synthesized which in turn binds with the operator region of the operon and prevents RNA polymerase from transcribing the operon. Identify the correct sequence of the structural genes in the lac operon.

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.
