The injection of a mixture of heat-killed smooth pneumococci and live rough pneumococci would result in the death of the mouse. This is because the heat-killed smooth pneumococci release their DNA into the surroundings, which can be taken up and incorporated by the live rough pneumococci, transforming them into smooth pneumococci. The newly transformed smooth pneumococci then cause disease and death in the mouse. This is what Griffith observed in his experiment, which demonstrated the phenomenon of bacterial transformation.
