B) the mouse will became fatally ill and live S strain bacteria will be detected in its blood 
C) the mouse's blood will contain live pathogenic R strain bacteria 
D) the dead S strain bacteria will transform to live R strain bacteria 
E) DNA from the live R strain bacteria will revive the dead S strain bacteria

Quizplus · Accepted Answer

If an injection to the mouse contains live R strain and heat-killed S strain Streptococcus pneumoniae, the mouse will become fatally ill and live S strain bacteria will be detected in its blood. This is because the heat-killed S strain bacteria release their DNA, which can be taken up by the live R strain bacteria and transform them into pathogenic S strain bacteria, leading to the death of the mouse.
