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 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. 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" 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 Experiments showed that DNA is the transforming principle not protein. Used X-ray crystallography showed photographs of DNA in an X surrounded by a circle indicating it was a helix.
