-Cells of mating type __ secrete a signaling molecule call __, which can bind to specific receptor proteins on nearby __ cells.
- At the same time, _ cells secrete _, which binds to receptors on __ cells.
W/o actually entering teh cells, the two mating factors cause the cells to grow toward each other and also bring about other cellular changes. The result is the __, or mating, of two cells of opposite type. The new __ cell contains all the genes of both original cells, a combination of ___ that provides advantages to the cell's descendants, which arise by subsequent __.
- chemical signaling
- a and alpha
- a factor
