In an experiment such as Griffith's pneumococcal experiment,which of the following,when injected into a mouse,would result in its death?
A) heat killed smooth pneumoccocci
B) live rough pneumococci
C) a mixture of heat killed smooth pneumococci and live rough pneumococci
D) a mixture of heat killed rough pneumococci and live rough pneumococci

Quizplus · Accepted Answer

Only the mice injected with a mixture of heat killed smooth pneumococci and live rough pneumococci died in Griffith's experiment. This is because the heat killed smooth pneumococci released their genetic material, including the virulence genes, which were taken up by the live rough pneumococci through transformation. This transformed the live rough pneumococci into virulent smooth pneumococci, causing the death of the mice. The other options listed do not contain the necessary components for this transformation to occur.
