Avery-MacLeod-McCarty experiment. How pneumococcus genetically transformed from avirulent to virulent form?

Durgapada Rana

In 1944, Oswald Avery, Colin MacLeod, and Maclyn McCarty revisited Griffith's experiment and concluded that the transforming material was pure DNA, not protein or RNA. These investigators found that DNA extracted from a virulent strain of the bacterium Streptococcus pneumoniae, also known as pneumococcus, genetically transformed an avirulent strain of this organism into a virulent form. 

 

Type IIR cells  ⇒ No transformation

Type IIR cells + Type IIIS DNA extract ⇒ Transformation

Type IIR cells + Type IIIS DNA extract + DNase ⇒ No transformation 

Type IIR cells + Type IIIS DNA extract + RNase ⇒ Transformation 

Type IIR cells + Type IIIS DNA extract + Protease ⇒ Transformation
