When experimenting with Streptococcus pneumoniae in the 1920s, Griffith concluded that some substance from the dead S strain bacteria passed to the R strain bacteria, imparting virulence and the ability to form a capsule. Avery and others continued the search for the substance that "transformed" the R strain into the S strain.Hypothesis I:Genetic material or "transforming substance" is protein.Hypothesis II:Genetic material or "transforming substance" is RNA.Hypothesis III:Genetic material or "transforming substance" is DNA.An experiment was performed that demonstrated that RNAase failed to prevent transformation of the R strain to S strain. This finding
A. supports Hypothesis I.
B. supports Hypothesis II.
C. supports Hypothesis III.
D. rejects Hypothesis I only.
E. rejects Hypothesis II only.
F. rejects Hypothesis III only.
G. does not support or provide information to reject any of these hypotheses.
