Match List – I with List – II.
| List - I | List - II |
| (A) Mature mRNA | (I) Adenylation |
| (B) Heterogeneous nuclear RNA | (II) Exons |
| (C) Tailing | (III) Methyl guanosine triphosphate |
| (D) Capping | (IV) RNA polymerase II |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
(A) Mature mRNA — this matches (II) Exons. After splicing only exons remain.
(B) Heterogeneous nuclear RNA — this matches (IV) RNA polymerase II. It transcribes hnRNA.
(C) Tailing — this matches (I) Adenylation. A poly-A tail is added at the 3′ end.
(D) Capping — this matches (III) Methyl guanosine triphosphate. Added at the 5′ end.
