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

According to Chargaff's rule, in a double-stranded DNA molecule, the quantity of adenine (A) precisely matches the quantity of thymine (T), and the quantity of cytosine (C) precisely matches the quantity of guanine (G). This complementarity arises from the specific hydrogen bonds established between these bases within the DNA structure.Consequently, the correct designation is Thymine (T).
