Question

Match List - I with List - II: 

 

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

Hint:

Adenine and guanine are purine bases, whereas cytosine, thymine, and uracil are pyrimidine bases. Purines have a double-ring structure, and pyrimidines have a single-ring structure.

Answer 1

The Correct Option is C

This question involves matching nitrogenous bases from nucleic acids (DNA/RNA) with their corresponding structures. - Adenine (A) is a purine base, so it corresponds to structure (III). - Cytosine (B) is a pyrimidine base, so it corresponds to structure (I). - Thymine (C) is a pyrimidine base found in DNA, so it corresponds to structure (IV). - Uracil (D) is a pyrimidine base found in RNA, so it corresponds to structure (II). Thus, the correct matching is: - (A)-(III), (B)-(I), (C)-(IV), (D)-(II). Final Answer: (3) (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
