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.
The Discovery of DNA's Structure. Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.atson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
