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. WebGriffith's Experiments using Streptococcus pneumonia rough and smooth strains concluded which of the following? a) DNA is the Molecule of Inheritance b) Some, yet unknown, factor of inheritance could be transferred from one bacteria to another. c) Protein if the Molecule of Inheritance d) Heat treating bacteria has NO effect on its virulence.

WebName: _____ Version 1 1. In the experiment performed by Frederick Griffith, mice were injected with one of two strains the bacteria that cause pneumonia. The smooth strain evaded the immune system and caused pneumonia, while the rough strain did not cause disease. However, if he killed the smooth strain with heat it would not cause disease.
