Observe the given figure and answer the question.
Match List - I with List - II.
| List - I | List - II |
|---|---|
| Structure | Label |
| (A) Methyl Guanosine Triphosphate | (I) F |
| (B) Intron | (II) I |
| (C) Poly A tail | (III) C |
| (D) Fully processed hn RNA | (IV) H |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
(A) Methyl Guanosine Triphosphate — this matches (III) C. C points to the cap (mGppp) added at the 5' end of the hnRNA.
(B) Intron — this matches (I) F. F points to the loops that are cut out during splicing.
(C) Poly A tail — this matches (IV) H. H is the tail of 200–300 adenylate residues added at the 3' end.
(D) Fully processed hn RNA — this matches (II) I. I points to the final molecule, the mRNA, ready to leave the nucleus.
