If a DNA molecule contains 30% cytosine, then 20% of the molecule should be thymine.
What do you mean by DNA?
DNA stands for deoxyribonucleic acid. It is considered as the genetic material of most organisms. It is a complex molecule that bears genetic information.
Amount of cytosine = 30%
According to Chargaff's rule, A=T, C=G.
∴ Guanine = 30%
Now A + T = 40%
Therefore, the amount of thymine molecules is 20%.
