In Griffith's experiments, what happened when heat- killed S- strain bacteria were injected into a mouse along with live R- strain bacteria?

A) RNA from the heat- killed S- strain was translated into proteins that killed the mouse.
B) Proteins released from the heat- killed S- strain killed the mouse.
C) DNA from the live R- strain was taken up by the heat- killed S- strain, converting them to R- strain and killing the mouse.
D) DNA from the heat- killed S- strain was taken up by the live R- strain, converting them to S- strain and killing the mouse.
