in the Griffith's experiment for transformation principle, when both the s strain and the r strain were injected into the blood of the mice ,could the r strain be isolated from the blood the dead mice.

i think it's not possible as r strains are deactivated by immune system of the mice but in wikipedia its written both r and s strain were isolated from the dead mice.

thank you

If you did this it would show that you had made an effort in constructing your question and encourage us to answer it. $\endgroup$ – David Aug 27 '19 at 18:28

S starin have capsule and cause infection. R starin have no capsule and not cause infection. According to griffith experiment S strain was killed by heat but R starin remain active, because S strain provide genatic information R strain. Then R strain use information to complete own structrure and reproduce itself.
