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.
Johann Friedrich Miescher was the first scientist who proposed the existence of a molecule that carries genetic information. He called it nuclein. But it was only in the 1950s that two young scientists, James Watson and Francis Crick, discovered the true genetic information carriers-molecules of DNA and RNA.NA is a single-stranded polymer. Its structure is similar to DNA except it has sugar ribose in place of deoxyribose and base uracil in place of thymine. During protein synthesis RNA molecules transfer genetic information from DNA molecules.
