Avery, MacLeod, and McCarty’s use of in vitro transformation

Description
Avery, MacLeod, and McCarty’s use of in vitro transformation to identify DNA as the most likely hereditary molecule. A purified extract from heat-killed SIII bacteria successfully transforms RII cells in the control experiment. Destruction of lipids and polysaccharides  , proteins  , or RNA does not affect transformation; however, destruction of DNA prevents transformationAvery, MacLeod, and McCarty’s use of in vitro transformation to identify DNA as the most likely hereditary molecule.
