Match List - I with List - II.
| List – I | List – II |
|---|---|
| (A) Operator | (I) RNA polymerase |
| (B) Promoter | (II) Permeability of the cell |
| (C) y-gene | (III) Hydrolysis of a specific disaccharide |
| (D) z-gene | (IV) Repressor protein |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
(A) Operator — this matches (IV) Repressor protein. The repressor binds the operator.
(B) Promoter — this matches (I) RNA polymerase. RNA polymerase binds the promoter.
(C) y-gene — this matches (II) Permeability of the cell. It codes for permease.
(D) z-gene — this matches (III) Hydrolysis of a specific disaccharide. It codes for β-galactosidase, which splits lactose.
