If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all thymine in a DNA molecule.
If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine will never be equal to the sum of all thymine in an RNA molecule.
