Question:
List-I List-II
Enzymes Products
(A) RNA polymerase I (I) hnRNA
(B) RNA polymerase III (II) hydrolysis of lactose
(C) RNA polymerase II (III) rRNA
(D) β-galactosidase (IV) tRNA, 5SrRNA, snRNA

Choose the correct answer from the options given below: 

Options:

(A) -(I), (B)- (II), (C)- (III), (D)- (IV)

(A) -(II), (B)- (III), (C)- (IV), (D)- (I)

(A) -(I), (B)- (II), (C)- (IV), (D)- (III)

(A) -(III), (B)- (IV), (C)- (I), (D)- (II)

Correct Answer:

(A) -(III), (B)- (IV), (C)- (I), (D)- (II)

Explanation:

The correct answer is Option (4) → (A) -(III), (B)- (IV), (C)- (I), (D)- (II)

List-I List-II
Enzymes Products
(A) RNA polymerase I (III) rRNA
(B) RNA polymerase III (IV) tRNA, 5SrRNA, snRNA
(C) RNA polymerase II (I) hnRNA
(D) β-galactosidase (II) hydrolysis of lactose

(A) The RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S).

(B) RNA polymerase III is responsible for transcription of tRNA, 5srRNA, and snRNAs (small nuclear RNAs).

(C) The RNA polymerase II transcribes precursor of mRNA, the heterogeneous nuclear RNA (hnRNA).

(D) The enzymes produced (mainly β-galactosidase, encoded by gene z) hydrolyze lactose into glucose and galactose, which can then be used by the bacteria as energy sources.
