Deoxyribonucleic acid (DNA) was shown to be the chemical substance of heredity by scientists working on bacteria (Avery et al., 1944). However, this molecule was poorly characterized, and early observations did not immediately explain how DNA worked. Since then, DNA has become iconic for genetics following the famous description of DNA structure by Watson and Crick (1953), who used chemistry and X-ray crystallography (Franklin and Gosling, 1953; Wilkins et al., 1953) to create their model. In this case, form explained function in a truly elegant fashion.
