Question

Match List-I with List-II:

List-I Transgene	List-II Used for/Products
(A) α-1-antitrypsin	(III) Treat emphysema
(B) cryIAc	(II) Corn borer
(C) Antisense RNA	(I) Meloidgyne incognitia
(D) cryIAb	(IV) Cotton bollworms

Choose the correct answer from the options given below:

• (A) - (III), (B) - (IV), (C) - (I), (D) - (II)
• (A) - (I), (B) - (II), (C) - (III), (D) - (IV)
• (A) - (III), (B) - (II), (C) - (I), (D) - (IV)
• (A) - (I), (B) - (IV), (C) - (III), (D) - (II)

Answer 1

The Correct Option is C

To solve the problem of matching List-I with List-II, we need to understand the role of each transgene:

• α-1-antitrypsin is a protein used in the treatment of diseases like emphysema, which is referenced by "Treat emphysema" (III).
• cryIAc is a gene from Bacillus thuringiensis used in genetically modified crops to control pests, specifically known for effectiveness against the Corn borer (II). 
• Antisense RNA is a strategy used in genetic engineering to create resistance against pests such as Meloidgyne incognitia, a type of root knot nematode (I).
• cryIAb is another Bacillus thuringiensis gene, effective against Cotton bollworms (IV).

Now we can match each transgene in List-I with its correct application in List-II.

List-I Transgene	List-II Used for/Products
(A) α-1-antitrypsin	(III) Treat emphysema
(B) cryIAc	(II) Corn borer
(C) Antisense RNA	(I) Meloidgyne incognitia
(D) cryIAb	(IV) Cotton bollworms

Thus, the correct answer is: (A) - (III), (B) - (II), (C) - (I), (D) - (IV).

Answer 2

The correct pair is (A) - (III), (B) - (II), (C) - (I), (D) - (IV)

• (A) α-1-antitrypsin is used to treat emphysema.
• (B) cryIAc is used against corn borers.
• (C) Antisense RNA is used to target Meloidegyne incognitia.
• (D) cryIAb targets cotton bollworms.

Explanation

Each statement highlights a specific application in the field of biology:

• α-1-antitrypsin is a protein that helps protect the lungs from damage and is used in the treatment of emphysema.
• cryIAc is a type of Bacillus thuringiensis (Bt) toxin used in genetically modified crops to protect against corn borers.
• Antisense RNA is a type of RNA molecule that can bind to specific mRNA molecules and inhibit their function, used here to target the nematode Meloidegyne incognitia.
• cryIAb is another type of Bt toxin used in genetically modified crops to target cotton bollworms.

Conclusion

These applications demonstrate the diverse ways in which biological research and technology can be utilized to address specific medical and agricultural challenges.
