Frederick Griffith conducted an experiment using 2 different strains of the bacterium Streptococcus pneumoniae. As you can see in the diagram below, the S strain bacteria killed the mice and the R strain bacteria did not kill the mice. What is the difference in structure between the S and R strains? Why does the dead mouse contain living S strain when only dead S strain was injected?
