Matching Pairs DNA ScientistsOnline version Match the Scientist with their contribution to the discovery of DNA. by Deanna Squire Squire 1 2 3 4 5 6 Used X-ray crystallography showed photographs of DNA in an X surrounded by a circle indicating it was a helix. Experiments showed that DNA is the transforming principle not protein. Confirmed that DNA is genetic material through experiments with a virus called bacteriophage. Concluded that some material must be transferred from heat-killed S bacteria to the live R bacteria. Called this material the "Transforming principle" Analyzed DNA of several organisms and found that the same four bases are found in the DNA of all organisms. Found that the amount of A = T and C = G. Influenced by data from other researchers to create a model of metal and wood to figure out the structure of DNA is a double helix twisted ladder
