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?
These four molecules are adenine (A), thymine (T), cytosine (C), and guanine (G). All genes are made up of stretches of these four bases (arranged in different ways and in different lengths). Photo: National Institute of Health. A critical feature of DNA is the ability of the nucleotides to make specific pairs: . Adenine pairs with Thymine and Cytosine pairs with Guanine. The human genome of Homo sapiens is stored on 23 chromosome pairs. 22 of these are autosomal chromosome pairs, while the remaining pair is sex-determining. The haploid human genome occupies a total of just over 3 billion DNA base pairs that means 6 billion base pairs per diploid cell.
