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.

Question

Quizplus · Accepted Answer

For successful mating in Saccharomyces cerevisiae, one cell must secrete a mating factor that is recognized by a complementary receptor on another cell. This ensures that cells of opposite mating types can identify and mate with each other, as one type secretes a factor that the other type's receptor can recognize and respond to, facilitating the mating process.
