NEET Botany Molecular Basis of Inheritance Questions Solved


If in a DNA molecule cytosine is 18%, the percentage of adenine would be:

(a) 18%                (b) 32%                (c) 36%                (d) 64%

A + G + C + T = 100%

Because  = G = 18%

A + 18% + 18% + T = 100%

A + T = 64%

as A = T

A = 32% and T = 32%

Therefore adenine would be 32%.
