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.
In 1962 at the Rockefeller University, in New York, New York, Hans Ris and Walter Plaut, using the electron microscope, discovered DNA in chloroplasts. In 1963, at the Rockefeller University, in New York, New York, Margit Nass and Sylvan Nass discovered DNA in mitochondria.ithin each mitochondrion is the mitochondrial DNA (mtDNA), which is different from the DNA in the cell's nucleus (nDNA). Organisms inherit their mitochondria only from their mothers via egg cells (oocytes).
