Question

Match List I with List II:

List I
A. α-1 antitrypsin
B. Cry IAb
C. Cry IAc
D. Enzyme replacement therapy

List II
I. Cotton bollworm
II. ADA deficiency
III. Emphysema
IV. Corn borer

Choose the correct answer from the options given below:
(1) A-II, B-I, C-IV, D-III
(2) A-III, B-I, C-II, D-IV
(3) A-III, B-IV, C-I, D-II
(4) A-II, B-IV, C-I, D-III

Accepted Answer

Correct Answer: C — A-III, B-IV, C-I, D-IIStep-by-step Solution:α-1 antitrypsin: A protein that protects the lungs from elastase; its deficiency causes emphysema. Hence, A matches with III (Emphysema).Cry IAb: A Bt toxin gene effective against corn borer (Lepidoptera). Hence, B matches with IV (Corn borer).Cry IAc: A Bt toxin gene effective against cotton bollworm. Hence, C matches with I (Cotton bollworm).Enzyme replacement therapy: Used to treat ADA (adenosine deaminase) deficiency in severe combined immunodeficiency (SCID). Hence, D matches with II (ADA deficiency).Thus, A-III, B-IV, C-I, D-II corresponds to option C.Key Concepts: Biotechnological applications: Bt toxins (Cry genes) for pest resistance, α-1 antitrypsin deficiency, enzyme replacement therapy for ADA deficiency.
