Experiment: Avery, MacLeod, and McCarty

DNA is the transferring principle; Discovery of RNase and DNase; Took away bacteria one at a time

Experiment: Franklin

DNA is helical in structure with more than one helix; Use of X-ray diffraction experiments

Experiment: Griffith

Bacteria can be transformed;Discovery of virulent and nonvirulent strains of some bacteria; Named the Transforming Process; Mixed Virul. &No

Experiment: Hershey & Chase

Bacteriophages use DNA as the infectious agent; Use of radioactive isotopes; Used 32P and 35S

Experiment: Chargaff

Determined the ratio of nitrogenous bases in various organisms;Quantitative analysis of DNA from different organisms.

Experiment: Watson and Crick

Described the Double Helix; Used X-ray crystallography results; Didn't perform new experiments; major grooves

Experiment: Meselson and Stahl

Determined the mode of DNA replication; Used heavy and light nitrogen
