WebIn Griffith's experiment, the mice were injected by both S (smooth Streptococcus)and R (rough Streptococcus) strains of the bacteria. 1) S strain → Injected into mice → Mice developed pneumonia and die. 2) R strain → Injected into mice → Mice live. 3) Heat-killed S strain → Injected into mice → Mice live. (heat kills the bacteria). Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.
