DNA molecule. Computer graphic representing a segment of the molecule Deoxyribonucleic Acid (DNA). This molecule contains all the inherited instructions necessary to produce a living organism. Atoms are shown as spheres. The DNA molecule is composed of two strands of atoms twisted into a helical shape. Each strand consists of an outer sugar-phosphate backbone (purple) from which nucleotide bases project inwardly (green). The bases consist of two purines (adenine,guanine) and two pyrimidines (thymine,cytosine). The bases are paired in a complementary fashion,making up the DNA genetic code | |
