- A.(A)-(IV), (B)-(III), (C)-(II), (D)-(I)✓
- B.(A)-(IV), (B)-(III), (C)-(I), (D)-(II)
- C.(A)-(IV), (B)-(I), (C)-(II), (D)-(III)
- D.(A)-(IV), (B)-(II), (C)-(III), (D)-(I)
Correct Answer
(A) (A)-(IV), (B)-(III), (C)-(II), (D)-(I)
Solution & Explanation
Answer: (1) (A)-(IV), (B)-(III), (C)-(II), (D)-(I) Solution: Gene therapy allows correction of a gene defect (IV); RNA interference (RNAi) is a method of cellular defence (III); ELISA detects HIV antigen/antibody, i.e. it is a diagnostic test for AIDS (II); Gel electrophoresis separates DNA fragments (I). This gives (A)-IV, (B)-III, (C)-II, (D)-I = option (1). NCERT Reference: Ch 10, p.180, line 13 — "RNAi takes place"; p.180, line 14 — "in all eukaryotic organisms as a method of cellular defense"
