Discovering DNA as the Hereditary Material
Scientists used two strains of a bacterium called the S-strain and the R-strain of a bacterium that causes pneumonia. The R-strain caused pneumonia when injected into mice and the S-strain was a safe strain that did not cause pneumonia.
The scientists injected the mice separately with the live S-strain (safe form) and dead R-strain (harmful form). In both cases the mice remained healthy.
