The number of adenine residues in the segment of DNA containing 20 base pairs. Concept introduction: Complementary base pairing describes the way in which the nitrogenous bases of the deoxyribonucleic acid (DNA) molecules align with each other. Complementary base pairing is also responsible for the double-helix structure of DNA. The double helical-structure of DNA consists of A, G, T, C, and the proportion of each of these bases in DNA is not random. The number of adenine bases in the DNA would always be equal to the number of cytosine bases. The rule %A=%T and %C=%G is known as the Chargaff’s rule. Instead of thymine, uracil (U) is found only in the RNA.
