Observe the diagram and answer the question.

Match List - I with List - II.
| List – I | List – II |
|---|---|
| (A) \(ori\) | (I) D |
| (B) \(tet^R\) | (II) B |
| (C) \(rop\) | (III) C |
| (D) \(amp^R\) | (IV) A |
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) \(ori\) — this matches (II) B. The origin of replication.
(B) \(tet^R\) — this matches (I) D. The gene containing the BamH I and Sal I sites.
(C) \(rop\) — this matches (IV) A. The gene for proteins taking part in plasmid replication, near Pvu II.
(D) \(amp^R\) — this matches (III) C. The gene containing the Pst I and Pvu I sites.
