After mixing A heat-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?

Phosphorescence in descendants of the living cells.

Explanation:

The DNA acts as the heritable molecule that pass down from the parents to their offsprings and move from one generation to the next generation. Different experiments had been done to identify the heritable molecules.

In an experiment, non fluorescent become fluorescent when mixed with the dead fluorescet cells. This means the material has been transformed to the non fluorescent cells. The phosphorescent acts as the descendants in the living cells and may be inherited to the future generations as well.
