Frederick Griffith's experiments with Streptococcus pneumoniae suggested that heat-killed bacteria could somehow "transform" live bacteria. This was the first evidence of DNA being the molecule of heredity, but it was not conclusively proven at the time. Griffith also observed that attenuated R (rough) bacteria could be transformed into the wild type (virulent) by DNA from dead virulent S (smooth) bacteria, providing evidence that bacteria could incorporate DNA from other bacteria.
