Question

DNA is formed using four kinds of base subunits. In a double-stranded segment of DNA, the percentage of the base C is 18%. What is the approximate percentage of base T?

Answer 1

The correct option is C 32%

According to Chargaff’s rule in a DNA molecule A = T and G = C and A + G + C + T = 100%. Here cytosine (C) is 18% hence G = 18%

∴

A + T = (100 – 36)%

∴

A + T = 64%

∴

A = 32%
