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?
Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. There are two groups of bases: Pyrimidines: Cytosine and Thymine each have a single six-member ring. Purines: Guanine and Adenine each have a double ring made up of a five-atom ring attached by one side to a six-atom ring. The order of nucleotides along DNA polymers encode the genetic information carried by DNA.
