WebbMice were killed because Q. Frederick Griffith accidentally discovered transformation when attempting to develop a vaccine for pneumonia. He injected mice with samples from S strain (virulent) and/or R strain (non-virulent) pneumococcal bacteria (Streptococcus pneumoniae). Which of the following results is NOT consistent with Griffith's Griffith's experiment, reported in 1928 by Frederick Griffith, was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.

WebbIn the transformation experiment by Griffith, injected virulent rough strain of S. pneumonia ( ROUGH) would kill mice while a non-virulent one ( SMOOTH) would cause no harm to the mice.
