During an investigation, researchers worked with mouse cells cultured in artificial media in dishes.The researchers found that mutant cells could not survive in a particular type of growth medium because they lacked the ability to synthesize a molecule critical for survival.Which investigation could be done to test whether intercellular transport could provide this molecule to cells?
A) Use electron microscopy to look for gap junctions between cells.
B) Measure the rate of radiolabeled molecule uptake by normal cells.
C) Test the survival rate of mutant cells when incubated with normal cells.
D) Test the ability of mutant cells to synthesize the molecule when incubated with normal cells.
E) Measure the size of the needed molecule to determine whether it could be transported between cells through gap junctions.

Incubating mutant cells with normal cells and testing their survival rate would determine if the normal cells can provide the critical molecule to the mutant cells through intercellular transport.
