Summary
Description	Griffith's experiment discovering a "transforming principle" in heat-killed virulent smooth pneumococcus that enables the transformation of rough non-virulent rough pneumococcus. I am declaring this to be CC0. Although you are not legally required to do so, I would appreciate if you credit me (Madeleine Price Ball) when using my work. --Madeleine (talk) 02:18, 23 January 2013 (UTC)
