As we learnt ,
Observation of experiment done by Griffith on mice -
He observed that heat-killed S-strain bacteria injected into mice did not kill them.
When he injected a mixture of heat-killed S and live R-bacteria, the mice died.
He also recovered living S bacteria from the dead mice.
S Strain (heat-killed) → inject into mice → mice live
S Strain (heat-killed) + R Strain (live) → inject into mice → mice die
