Cells of the Yeast Saccharomyces Cerevisiae Use Chemical Signalling to Identify

Multiple Choice

Cells of the yeast Saccharomyces cerevisiae use chemical signalling to identify individuals of the opposite mating type and initiate the mating process. Each cell secretes a mating factor that binds to receptor proteins on the other cell. You would expect successful mating to occur between cells with

A) identical mating factors and receptor proteins.
B) identical mating factors and complementary receptor proteins.
C) complementary mating factors and identical receptor proteins.
D) complementary mating factors and receptor proteins.
E) complementary mating factors and cAMP receptors.
