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. WebbGriffith found transformation with his experiment. Transformations were demosntrated in the form of dead mice with a rough strain of Pneumococci. Once he fused rough strain …

WebbGriffith'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. robert townsend softbank
