D ) DNase , an enzyme that destroys DNA , eliminated the biological activity of the transforming material.
S strain was used and incoporated into different tube containing different enzyme.
1 tube ( S strain + protease ) = mouse die
2 tube ( S strain + RNase )=mouse die
3 tube ( S strain + DNase )= mouse alive
because the transforming material is degraded by the DNase and allow the mouse to survive . This show that the transforming material is DNA and not protein.

1.) Briefly explain the general procedure and purpose of the Griffth Transformation experiement. 2.) If Avery, Macleod, and McCarty had found that samples of heat-killed bacteria treated with RNase and DNase transformed bacteria, but samples treated with protease did not, what conclusion would they have made?

1. Griffiths (1928) mixed heat-killed 'THIS' bacteria with 'IIR' 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? When 'R' and 'strains were mixed, the DNA from 'IS' bacteria with the gene responsible for forming capsules transferred to the 'R' bacteria. The gene cause 'R' to transform into...
