Question:

After mixing a heat-killed, phosphorescent strain of bacteria with a living non-phosphorescent strain, you discover that some of the living cells are now phosphorescent. Which observations would provide the best evidence that the ability to fluoresce is a heritable trait?

A) DNA passed from the heat-killed strain to the living strain.

B) Protein passed from the heat-killed strain to the living strain.

C) The phosphorescence in the living strain is especially bright.

D) Descendants of the living cells are also phosphorescent.

E) Both DNA and protein passed from the heat-killed strain to the living strain.

Answer:

D) Descendants of the living cells are also phosphorescent.
