Describe your reasoning. As guanine and cytosine are complementary, another 15% of the nucleotides must have cytosine. The remaining 70% of the nucleotides (100%-30%) must have adenine and thymine in equal proportions (35% each), as they are complementary to each other.f 15% of the nucleotides in a DNA molecule contain guanine, what percentage of the nucleotides having each of the other three bases?
Like DNA, RNA contains the bases adenine (A), cytosine (C), and guanine (G); however, RNA does not contain thymine, instead, RNA's fourth nucleotide is the base uracil (U).he nitrogenous bases of DNA are adenine (A), guanine (G), cytosine (C) and thymine (T). RNA also has the bases A, G and C-but has uracil (U) instead of T. 7 people found this useful. Edit.
