WebThis is called transformation, and shows that DNA is the “transforming principle.”. This is also what enables certain bacteria to become immune to certain antibiotics. Once a … 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.
