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 correct matches are:

• A. Genetically engineered host cell - II. A genetically modified organism (GMOs) is inserted into a host cell for manipulation.
• B. GM cotton - IV. GM cotton uses *Bacillus thuringiensis* for pest resistance.
• C. Gene therapy - I. Gene therapy is used to treat ADA deficiency (Adenosine Deaminase deficiency).
• D. ELISA (enzyme-linked immunosorbent assay) - III. ELISA is based on antigen-antibody interactions to detect specific proteins or antigens.

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