DNA double helix, with the "ladder rungs" — which are nucleotides composed, in part, by the base pair that forms each "rung." DARK BLUE represents Thymine, and is normally bonded to Adenine (LIGHT BLUE). DARK GREEN represents Guanine, and is normally bonded to Cytosine (LIGHT GREEN). A mutation results when bonding of the base pairs diverges from this standard bonding of complementary bases. In addition to the base pairs, each DNA nucleotide consists of a deoxyribose sugar  molecule and a phosphate group. It is the sugar-plus-phosphate that forms the helical ribbon structure, sometimes referred to as the "backbone" of the DNA molecule.
