WebGriffith's Experiment was an experiment done in 1928 by Frederick Griffith. It was one of the first experiments showing that bacteria can get DNA through a process. Griffith used two strains of Streptococcus pneumoniae. He then uses the bacteria to infect the mice, which have many similar characteristics to humans. WebOswald T. Avery, an American pneumococcal researcher, speculated that Griffith’s experiment lacked appropriate control.
