Question

According to Chargaff's Rule, in a DNA molecule, the amount of adenine (A) is always equal to the amount of ______.

• A. Cytosine (C)
• B. Guanine (G)
• C. Thymine (T)
• D. Uracil (U)

Hint:

Chargaff’s rule is essential for understanding the structure of DNA, as it helps explain the complementary base pairing in the double helix structure.

Answer 1

The Correct Option is C

Chargaff's rule states that in a double-stranded DNA molecule, the amount of adenine (A) is always equal to the amount of thymine (T), and the amount of cytosine (C) is always equal to the amount of guanine (G). This pairing is due to the specific hydrogen bonds formed between the bases in the DNA structure. Thus, the correct answer is Thymine (T).
