List-I (Genes/Products) | List-II (Used in/for) |
(A) C-Peptide | (I) Corn borer |
(B) α-1-antitrypsin | (II) Rosie |
(C) cryIAc | (III) Insulin |
(D) α-lactalbumin | (IV) Emphysema |
Let's match the genes/products with their corresponding uses:
(A) C-Peptide: C-Peptide is a part of insulin that is released from the pancreas. It is cleaved from the proinsulin molecule and is used as a marker in monitoring insulin production. Thus, (A)-(III) is correct, as C-Peptide is related to insulin.
(B) α-1-antitrypsin: This protein is used in the treatment of emphysema, a lung condition often caused by a deficiency of this protein. It is used as a therapeutic product to prevent damage to lung tissue. Thus, (B)-(IV) is correct, as α-1-antitrypsin is used for treating emphysema.
(C) cryIAc: CryIAc is a Bt toxin protein produced by the bacterium Bacillus thuringiensis, which is used as an insecticide, particularly for targeting pests like the corn borer. Thus, (C)-(I) is correct, as cryIAc is used for the corn borer.
(D) α-lactalbumin: α-lactalbumin is a protein found in milk, and it has been used in genetic modifications to produce Rosie, the genetically modified cow that produces human-like milk for pharmaceuticals. Thus, (D)-(II) is correct, as α-lactalbumin is associated with Rosie.
Thus, the correct matching is:
(A)-(III): C-Peptide → Insulin
(B)-(IV): α-1-antitrypsin → Emphysema
(C)-(I): cryIAc → Corn borer
(D)-(II): α-lactalbumin → Rosie
The correct answer is (2) (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
