DNA molecule. Computer artwork representing part of a strand of DNA (deoxyribonucleic acid). Atoms are seen as spheres. DNA contains all the inherited instructions necessary for the development and functioning of living organisms. The DNA molecule is composed of two spiral strands of sugar phosphates (red and pink), joined by pairs of cross-linking nucleotide bases (blue). It is the sequence of these bases that makes up the genetic code in the form of genes, segments of DNA that code for particular characteristics.
