The Griffith Experiment Pearson+ Channels

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. http://opportunities.alumdev.columbia.edu/griffith-mice-experiment.php WebVarious experiments were performed to establish DNA (deoxyribonucleic acid) as the genetic material. Frederick Griffith in 1982 aimed to prove that there was a transforming principle in the genes of bacteria. He believed that bacteria were capable to perform transmission of information from one strain to another by a process called transformation. ps3 game pkg converter
