Guanine and cytosine share a bond of hydrogen that is triple in its structure and . If all adenine bonds to thymine and all cytosine pairs with guanine, then the sum of all adenine equals the sum of all thymine in a DNA molecule. All of the components of ribonucleic acid are identical to those of DNA, with only two exceptions. Thymine and uracil are distinguished by merely the presence or absence of a methyl group on the fifth carbon (C5) of these heterocyclic six-membered rings. The bases can divide into two categories: A nucleotide consists of one of the five bases above connected to a sugar (either ribose or deoxyribose) and a phosphate group. When examining the basic components of DNA, the mole percentage of guanine is comparable to cytosine and the mole percentage of adenine is according to thymine [3].
