Evidence of Transformation of R Strain Cells by Biomolecules from S

Multiple Choice

Evidence of transformation of R strain cells by biomolecules from S strain cells includes:

A) the R strain cells begin to produce high levels of neurotoxin.
B) the transformed R strain cells gain the ability to kill mice.
C) isolation of smooth-looking cells from animals infected with R strain cells that had been incubated with heat-killed S strain cells.
D) the R strain cells produce neurotoxin and gain the ability to kill mice
E) the R strain cells gain the ability to kill mice,and smooth-looking cells were isolated from animals infected with R strain cells previously incubated with heat-killed S strain cells.
