In Griffith’s experiments, what happened when heat-killed S-strain bacteria were injected into a mouse along with live R-strain bacteria?
A. DNA from the live R-strain was taken up by the heat-killed S-strain, converting them to R-strain and killing the mouse.
B. DNA from the heat-killed S-strain was taken up by the live R-strain, converting them to S-strain and killing the mouse.
C. Proteins released from the heat-killed S-strain killed the mouse.
D. RNA from the heat-killed S-strain was translated into proteins that killed the mouse.
