| (V) Escherichia coli |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (A)-(III), (B)-(I), (C)-(II), (D)-(V)
(A) Produces crystals of toxic insecticidal proteins — this matches (III) Bacillus thuringiensis. It forms Bt toxin crystals.
(B) Nematode which infects the roots of tobacco plant — this matches (I) Meloidegyne incognitia. Controlled by RNA interference.
(C) Vector used to transfer the nematode specific gene into the host plant was obtained from — this matches (II) Agrobacterium tumefaciens. Its Ti plasmid is used as the vector.
(D) Plasmids used to produce the insulin chains were obtained from — this matches (V) Escherichia coli. Eli Lilly used E. coli plasmids.
(IV) Propionibacterium sharmanii (Swiss cheese) matches none.
