Work

The substances known as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are found in nearly all cells in almost all organisms. Since its discovery in 1869, it was suspected that DNA had an important biological function. Long before it was confirmed that DNA was the bearer of organisms' genetic material, Albrecht Kossel began to investigate the chemical compositions and properties of nucleic acids. Between 1885 and 1901, Kossel discovered that these acids were composed of five nitrogen bases: adenine, cytosine, guanine, thymine, and uracil.
