Question

Match List-I with List-II:

List-I	List-II
A. Genetically engineered Human Insulin	I. Gene therapy
B. GM Cotton	II. E. coli
C. ADA Deficiency	III. Antigen-antibody interaction
D. ELISA	IV. Bacillus thuringiensis

Choose the correct answer from the options given below:

• A. A-III, B-II, C-IV, D-I
• B. A-II, B-I, C-IV, D-III
• C. A-IV, B-III, C-I, D-II
• D. A-II, B-IV, C-I, D-III

Answer 1

The Correct Option is D

The accurate pairings are:

• A. Genetically engineered host cell - II. A genetically modified organism (GMO) is introduced into a host cell for modification.
• B. GM cotton - IV. GM cotton incorporates *Bacillus thuringiensis* to confer pest resistance.
• C. Gene therapy - I. Gene therapy is employed in the treatment of ADA deficiency (Adenosine Deaminase deficiency).
• D. ELISA (enzyme-linked immunosorbent assay) - III. ELISA relies on antigen-antibody interactions for the detection of specific proteins or antigens.

Consequently, the correct selection is (4): A-II, B-IV, C-I, D-III.
