Transforming Principle - Griffith

WebGriffith’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 called transformation. In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria. flutter stateless stateful widget
