Match List-I with List-II
| List-I | List-II |
|---|---|
| Enzymes | Functions |
| (A) RNA polymerase I | (I) tRNA |
| (B) RNA polymerase II | (II) 18S rRNA |
| (C) RNA polymerase III | (III) hnRNA |
| (D) β-galactosidase | (IV) Hydrolysis of lactose |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A) - (II), (B) - (III), (C) - (I), (D) - (IV)
(A) RNA polymerase I — this matches (II) 18S rRNA. In eukaryotes this enzyme makes most of the rRNAs, including 18S, 28S and 5.8S rRNA.
(B) RNA polymerase II — this matches (III) hnRNA. It makes the primary transcript of mRNA, which is called heterogeneous nuclear RNA.
(C) RNA polymerase III — this matches (I) tRNA. It makes tRNA, 5S rRNA and snRNAs.
(D) β-galactosidase — this matches (IV) Hydrolysis of lactose. This enzyme of the lac operon breaks the sugar lactose into galactose and glucose.
