WebFrederick Griffith was a British bacteriologist known for his experiment that demonstrated the principle of transformation in pneumonia-causing bacteria. When this experiment, (now known as Griffith Experiment, first reported by Griffith in 1928), was investigated in detail, years later, it led to the elucidation of the role of DNA in heredity. WebJun 12, 2016 · Griffith Experiment. In 1928, Frederick Griffith performed a DNA experiment using pneumonia bacteria and mice. This experiment provided evidence that some particular chemical within cells is genetic material. The objective of the experiment was to find the material within the cells responsible for the genetic codes.
