Isolated and identified nucleic acid.
Performed first major experiment which led to discovery of DNA.
Created and analyzed mutants of Neurospora. Showed how genes direct the synthesis of enzymes that control metabolic processes.
Discovered that DNA is the substance that causes bacterial transformation.
Helped us to know 1 rule of DNA. C = G, A = T.
Contributed to scientific understanding of phosphorescence isotope, separation, optical microscopy, and x-ray diffraction.
Figured out double helix shape of DNA.
Took x-ray diffraction images of DNA.
Broke down genetic code.
