Match List - I with List - II.
| List - I | List - II |
| (A) Cloning vector | (I) Sea weeds |
| (B) \(\beta\)-galactosidase | (II) Selectable marker |
| (C) Agarose | (III) Ti-plasmid of Agrobacterium tumefaciens |
| (D) ampR in pBR322 | (IV) Chromogenic screening |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
(A) Cloning vector — this matches (III) Ti-plasmid of Agrobacterium tumefaciens. Modified into a vector.
(B) \(\beta\)-galactosidase — this matches (IV) Chromogenic screening. Blue and colourless colonies tell recombinants apart.
(C) Agarose — this matches (I) Sea weeds. Agarose is extracted from sea weeds.
(D) ampR in pBR322 — this matches (II) Selectable marker. Ampicillin resistance selects transformants.
