What changed

Purified a pneumococcal transforming fraction and presented chemical and enzymatic evidence that its activity resided principally in DNA.

Scientific scope

Purified a pneumococcal transforming fraction and presented chemical and enzymatic evidence that its activity resided principally in DNA. Scope limitation: The result concerns the tested bacterial transformation system and the detection limits of the methods. It does not alone resolve every mechanism of heredity.
