After 15 years, Avery and his colleagues, Colin MacLeod and Maclyn McCarty, purified the “transforming principle” and demonstrated that DNA was the active ingredient. A series of chemical tests were done that showed that the material passed on had all the chemical properties of DNA. Enzymes that destroy proteins and RNA had no effect on the transformation of harmless bacteria to pathogenic bacteria, but enzymes that destroy DNA inactivated the transformation. A paper stating the findings of Avery and his team was released in 1944, but little attention was drawn from
