Vedclass · Answer

(C) The transformation experiments conducted by Frederick Griffith on $Streptococcus$ $pneumoniae$ (Pneumococcus) were further refined by Avery, MacLeod, and McCarty. They purified biochemicals (proteins, $DNA$, and $RNA$) from the heat-killed $S$ strain to see which one could transform live $R$ strain bacteria into $S$ strain. They discovered that digestion of protein and $RNA$ with enzymes did not affect transformation, but digestion with $DNase$ inhibited the transformation process. This conclusively proved that $DNA$ is the hereditary material responsible for transformation.

The transformation experiments on Pneumococcus showed that:
