What evidence supported the claim of Avery and colleagues that DNA was the “transforming principle” in bacterial virulence? a. It exhibited a host of chemical properties that were characteristic of DNA. b. Tests of various enzymes indicated that only those enzymes that digested DNA inactivated the transforming principle. c. All of those d. Bacteriophage confirmed that release of DNA from phages was responsible for infection.
