Griffiths (1928) mixed heat-killed 'S' bacteria with 'R' bacteria and injected a mouse with both types of bacteria. As a result, the mouse died and Griffiths obtained living 'S' bacteria from the dead mouse. How can you explain this phenomenon? -️️The DNA from the 'S' bacteria with the gene responsible for capsule formation was transferred to the 'R' bacteria when the strains were mixed. This gene transformed the 'R' bacteria into 'S' bacteria, allowing it to produce a cap...
