C) living bacteria could incorporate hereditary material from killed bacteria.
D) the mice became resistant to the deadly bacteria.

Question

Quizplus · Accepted Answer

Griffith's experiments showed that living bacteria could incorporate hereditary material from killed bacteria, which ultimately resulted in a transformation of genetic traits of the living bacteria. This transformation was demonstrated by the conversion of non-pathogenic bacteria into pathogenic bacteria in the presence of DNA from pathogenic bacteria when mixed together.
