Oswald Avery (c.1930)

In a very simple experiment, Oswald Avery's group showed that DNA was the "transforming principle." When isolated from one strain of bacteria, DNA was able to transform another strain and confer characteristics onto that second strain. DNA was carrying hereditary information. With DNA as the hereditary molecule, the stage was set for one of the most exciting periods in DNA science: understanding DNA structure and function.
