Question

In Griffith's experiment, why were S-type cells virulent and R-type cells not virulent? S-type cells have DNA, and R-type cells do not. S-type cells could not be killed by heat treatment, and R-type cells could. S-type cells have a protective smooth capsule, and R-type cells do not. S-type cells contain the transforming substance, and R-type cells do not. S-type cells were resistant to DNase treatment, and R-type cells were not.
