WebBased on these observations, Griffith hypothesized that a chemical component from the virulent S cells had somehow transformed the R cells into the more virulent S form (Griffith, 1928). WebIn the critical experiment, Frederick Griffith ( 1928) mixed heat-killed S with live R and injected the combination into mice: the mouse died.The dead mouse's tissues were found to contain live bacteria with smooth coats like S.
