Question

Quizplus · Accepted Answer

Nutrients, mating factors, and cell size are all involved in regulating START in yeast. Nutrient availability determines if there are enough resources for cell growth and division, mating factors signal whether there are potential mating partners present, and cell size determines if the cell is big enough to divide. Thus, all of the above factors are important in regulating START in yeast.
