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.
Adenine (A) is one of four chemical bases in DNA, with the other three being cytosine (C), guanine (G), and thymine (T).Within the DNA molecule, adenine bases located on one strand form chemical bonds with thymine bases on the opposite strand.The sequence of four DNA bases encodes the cell's genetic instructions.A form of adenine called adenosine triphosphate (ATP) serves as an energy storage molecule and is used to power many chemical reactions within the cell.he sequence of four DNA bases encodes the cell's genetic instructions.
