| Column-I | Column-II |
|---|---|
| (a) Beta-galactosidase | (i) Inducer in lac operon |
| (b) Repressor protein | (ii) Prevents transcription |
| (c) Lac operon | (iii) Regulates gene expression |
| (d) Lactose | (iv) Substrate for enzyme |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-iv, c-i, d-iii
C
a-iii, b-i, c-iv, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
Beta-galactosidase acts on lactose, which is the substrate that induces the lac operon. The repressor protein prevents transcription by binding to the operator, thereby regulating the expression of the operon. This matches the descriptions given in the context.
