In Griffith's pneumococcal experiment, the heat-killed smooth pneumococci would not cause death on their own because they cannot cause disease. Similarly, live rough pneumococci would not cause death, as they do not possess the necessary polysaccharide capsule to evade the host immune system. However, a mixture of heat-killed smooth pneumococci (which provide the genetic information for capsule synthesis) and live rough pneumococci (which can now produce a capsule due to the genetic information uptake) can result in death due to the formation of virulent, encapsulated bacteria.
