Answered by The Community. Making the world better, one answer at a time. If the DNA macromolecule contains 20% G (guanine), then by Watson-Crick complementarity it must contain 20% C (cytosine). Together this equals 40%, so the percent that is A (adenine) and T (thymine) together is 60%.By Watson-Crick complementarity, then, the percent A in the molecule is half of 60: 30%.0 %. Adenine pairs with thymine-therefore if 20% is A, another 20% percent will be T. Only two other bases are left, which form pairs: guanine and cytosine, in equal quant â¦ ities.

Because these base pair they will have a 1:1 ratio meaning the 70% will be divided in two so, 35% thymine, 35% adenine.Source(s): just now. Report Abuse. Remember, guanine binds to cytosine and adenine binds to thymine. Therefore, if 15% of DNA is guanine, 15% of DNA has to be cytosine. The rest of the DNA (100-30=70) must be thymine and adenine. 70/2 = 35% for thymine and adenine.
