the \transforming substance\ that provides r-strain bacteria with the genetic information to become like s-strain bacteria is:
○ viral dna
○ sulfur
○ rna
○ protein
○ bacterial dna

Explanation:

The transforming principle experiment (Avery - MacLeod - McCarty) showed that the substance responsible for transforming R - strain bacteria to S - strain is bacterial DNA. Viral DNA is not involved in bacterial transformation between R and S strains. Sulfur is a component in some viral experiments (like Hershey - Chase) but not in this bacterial transformation. RNA and protein were ruled out as the transforming substance in the Avery et al. experiment.

Answer:

E. bacterial DNA
