Question

Match List - I with List - II:

List - I	List - II
(A) Adenine	(I)
(B) Cytosine	(II)
(C) Thymine	(III)
(D) Uracil	(IV)

 

Choose the correct answer from the options given below:

• 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).
