Strain

On gradual loading , stress - strain relationship for a metal wire is as follows . Within proportionality limit , stress prop strain or, "Stress"/"strain" = a constant for the material of wire. Just on crossing the yield region, the material will have

Recall the experiment done by Frederick Griffith. If RNA, instead of DNA was the genetic material, would the heat killed strain of strep have transformed the R-strain into virulent strain? Explain your answer.
