In the yeast signal transduction pathway, after both types of mating cells have released the mating factors and the factors have bound to specific receptors on the correct cells,
A- the cell membranes fall apart, releasing the mating factors that lead to new yeast cells.
B- the cells then produce the a factor and the factor.
C- one cell nucleus binds the mating factors and produces a new nucleus in the opposite cell.
D- a growth factor is secreted that stimulates mitosis in both cells.
E- binding induces changes in the cells that lead to cell fusion.
Answer: E
