Answer:
In his experiment, Griffith used two strains of Streptococcus pneumoniae type II- rough(R) strain and a type III smooth(S) strain. The type III smooth strain had an outer polysaccharide capsule which makes smooth strain a virulent strain.
So in his experiment, Griffith injected these strains in mice in an order and observed the result. When he
injected living S strain- Mice died
Injected living R- strain- Mice survived
Injected heat-killed S strain- Mice survived
Injected heat S strain+ living R strain- Mice died
So after his experiment, he concluded that R strain took something from heat killed S strain which transformed the R strain into virulent strain that killed the Mice. So based on this experiment Griffith gave transformation principle.
