WebOswald Avery, Colin MacLeod, and Maclyn McCarty conducted their experiment as a continuation of Griffith’s experiment. They treated the heat killed virulent S strain cells with proteases, RNases, Lipases, and DNases. The biomolecules were then tested for the transformation of the R strain cell. The results are as follows: WebThe results of the Griffith experiment are shown in the diagram below.

WebThen, Griffith killed the Strep cells with heat prior to injection; in this case, the heat-killed S cells had no effect. Finally, Griffith injected a mixture of live R cells and heat-killed S cells. What were the results and conclusions of this experiment?
