Yоu hаve isоlаted а mutant in which a fractiоn of the new cells die soon after cell division, and a fraction of the living cells have an extra copy of one or more chromosomes. When you grow the cells under conditions where they transit the cell cycle more slowly, the defect disappears, suggesting that the mitotic spindle and segregation machinery are normal. 1) What checkpoint may be defective in the cell cycle of the mutant? Explain your reasoning. 2) Describe in great detail the normal operation of such checkpoint.
