DNA stands for deoxyribonucleic acid. It has a double strand that contains the genes (a hereditary material) of the organism. It was discovered by James Watson and Francis Crick. Their double-helix structure was based on x-ray diffraction image named as Photograph 51 or Photo 51. It was taken by Raymond Gosling, a pHD student under the supervision of Rosalind Franklin. They used this photo to determine the chemical and physical structure of the DNA and the bond that links the genes altogether. The answer is Rosalind Franklin
