DNA helix. Computer artwork of part of a strand of DNA (deoxyribonucleic acid). The DNA molecule is composed of two spiral strands of sugar phosphates. These are held together by complementary pairs of four cross-linking nucleotide bases (rods). These are adenine, cytosine, guanine, thymine. The sequence of bases makes up the unique genetic code of every individual cellular organism.
