Frederick Griffith | This person made an experiment that involved injecting mice with pneumonia: smooth S cells‚ rough R cells‚ heat-killed S cells‚ and heat-killed S cells with living R cells. | Avery‚ McCarty‚ and MacLeod | First to show that DNA was the genetic material‚ but not believed. Repeated Griffith’s experiment‚ but subjected the strains to different enzymes‚ isolating RNA‚ DNA‚ lipids‚ carbohydrates‚ and proteins. Only the DNA killed the mice; the others had the mice survive. | Hershey
