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?
Guanine is the other purine nucleotide in DNA. Guanine pairs with cytosine in the DNA structure. Guanine differs from adenine in that it is made up of oxygen in addition to carbon, hydrogen and nitrogen. Like adenine, guanine consists of two rings, one with five members and one with six. Guanine also allows for synthesis of glucose when it is the nitrogenous base for guanosine triphosphate.
