Important Questions on Molecular Basis of Inheritance
Read the following statements with respect to lac operon, and select the correct option.
A. It has three structural genes.
B. Glucose can act as an inducer.
C. Repressor protein acts in the presence of lactose.
D. Repressor is synthesized by the regulator gene.
The figure shows the structure of lac operon with the four parts labelled A, B, C, and D. Select the option in which the parts are identified correctly.
Match the column I with column II for genes of lac operon and select the correct option.
| Column - I | Column - II |
| A. Z gen | (i) Transacetylase |
| B. Y gene | (ii) Repressor |
| C. A gene | (iii) - Galactosidase |
| D. i gene | (iv) Permease |
i. Each operon has its specific operator and specific repressor.
ii. The y gene codes for permease, which increases the permeability of the cell to beta-galactoside.
iii. Regulation of lac operon can be visualized as regulation of enzyme synthesis by its substrate.
Select the option with the correct statements.
