Dr. Griffith found that if he mixed heat-killed smooth-phenotype Streptococcus pneumoniae cells (S strain) with living, rough-phenotype cells (R strain) before injecting them into mice, the mice would die. He also observed live R cells carrying the S-type capsule in the blood of these mice.

But what if, when he mixed the heat-killed S strain with the live R strain, there were DNA endonucleases and exonucleases present?

Group of answer choices

a. The mice would live and he would isolate S strain cells from their blood.

b. The mice would die and he would isolate R strain cells with S-type capsule from their blood.

c. The mice would live and he would isolate no cells from their blood.

d. The mice would live and he would isolate R strain cells from their blood.

e. The mice would live and he would isolate R strain cells with S-type capsule from their blood.

f. The mice would die and he would isolate S strain cells from their blood.
