Avery, MacLeod, and McCarty showed that DNA was the transforming principle by demonstrating that mice survived
when injected with a mixture of dead virulent bacteria and live nonvirulent bacteria that were treated with a DNA
degrading enzyme. If RNA was the genetic material, what would have been the effect on the mice? Why?
What will be an ideal response?
ANSWER: The mice would die because DNA would be degraded but not RNA. Thus, if RNA was the
genetic material, it would still be present and able to transform the nonvirulent bacteria to
virulent bacteria. The newly transformed bacteria would subsequently kill the mice.
