The discovery of DNA focused scientists' efforts and led to the research into genetics and heredity aimed at improving life on Earth today. Identification of DNA DNA's discovery can be traced to 1868, when Swiss medical student Johann Friedrich Miescher began work on isolating proteins from white blood cells.
Indeed, they had. That very morning, the two men worked out the double helix structure of deoxyribonucleic acid, better known to every first-grader as DNA. Mind you, they did not discover DNA. That scientific feat was actually accomplished in 1869 by Friedrich Miescher, a physiological chemist working in Basel, Switzerland. Miescher determined that DNA, a nucleic acid found in the cell's nucleus, was comprised of sugar, phosphoric acid, and several nitrogen containing bases.
