Match List-I with List-II:
| List-I | List-II |
|---|---|
| Transgene | Used for/Products |
| (A) α-1-antitrypsin | (I) Meloidogyne incognita |
| (B) cryIAc | (II) Corn borer |
| (C) Antisense RNA | (III) Treat emphysema |
| (D) cryIAb | (IV) Cotton bollworms |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(III), (B) - (IV), (C) - (I), (D)-(II)
(A) α-1-antitrypsin — this matches (III) Treat emphysema. Transgenic animals are used to produce the human protein α-1-antitrypsin. This protein is used to treat emphysema, a lung disease.
(B) cryIAc — this matches (IV) Cotton bollworms. The proteins coded by the genes cryIAc and cryIIAb control the cotton bollworms, so these genes are put into Bt cotton.
(C) Antisense RNA — this matches (I) Meloidogyne incognita. Nematode-specific genes put into tobacco make both sense and antisense RNA. The two strands pair into double-stranded RNA, which silences the mRNA of the nematode. The parasite cannot survive in the tobacco roots. This is RNA interference.
(D) cryIAb — this matches (II) Corn borer. The protein coded by cryIAb kills the corn borer, so this gene is used in Bt corn.
