Match List - I with List - II.
| List - I | List - II |
|---|---|
| (A) RNA Polymerase II | (I) 28S rRNA |
| (B) RNA Polymerase I | (II) hnRNA |
| (C) Ribozyme | (III) 5S rRNA |
| (D) RNA Polymerase III | (IV) 23S rRNA in bacteria |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
(A) RNA Polymerase II — this matches (II) hnRNA. RNA polymerase II transcribes the precursor of mRNA, the heterogeneous nuclear RNA.
(B) RNA Polymerase I — this matches (I) 28S rRNA. RNA polymerase I transcribes the rRNAs (28S, 18S and 5.8S).
(C) Ribozyme — this matches (IV) 23S rRNA in bacteria. In bacteria the 23S rRNA acts as the enzyme (ribozyme) that forms peptide bonds.
(D) RNA Polymerase III — this matches (III) 5S rRNA. RNA polymerase III transcribes tRNA, 5S rRNA and snRNAs.
