Aheat-killed, phosphorescent light emitting) strain of bacteria is mixed with a living, non-phosphorescent strain. Further observations of the mixture show that some of the living cells are now phosphorescent. Which of the following observations would provide the best evidence that the ability to phosphoresce is a heritable trait? a. phosphorescence in descendants of the living cells b. evidence that DNA was passed from the heat-killed strain to the living strain c. evidence that protein passed from the heat-killed strain to the living strain d. especially bright phosphorescence in the living strain
e. the trait would be heritable if someone put it in their will,
