Match List-I with List-II
| List-I | List-II |
|---|---|
| (A) Bt Cotton | (I) Functional ADA cDNA |
| (B) Method of Cellular defense | (II) 'A' peptide |
| (C) Genetically engineered insulin | (III) RNAi |
| (D) Gene therapy | (IV) Insecticidal protein |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
(A) Bt Cotton — this matches (IV) Insecticidal protein. Bt cotton carries cry genes of Bacillus thuringiensis, so it makes the Bt toxin protein that kills bollworms.
(B) Method of Cellular defense — this matches (III) RNAi. RNA interference takes place in all eukaryotes as a method of cellular defence, silencing a specific mRNA.
(C) Genetically engineered insulin — this matches (II) ‘A’ peptide. Eli Lilly made the A and B chains separately in E. coli and joined them by disulphide bonds.
(D) Gene therapy — this matches (I) Functional ADA cDNA. In the first gene therapy, a working ADA cDNA was put into the patient’s lymphocytes to treat adenosine deaminase deficiency.
