The cell cycle is divided into several phases.
In this figure, M indicates mitosis, when the nucleus is dividing, and G1, S, and G2 are parts of interphase. Points X, Y, and Z represent checkpoints during these phases.
What happens during cell cycle checkpoints?
Chemical signals tell the cell to proceed with division or to stop.
Chemical signals tell the cell when to translocate DNA.
Chemical signals tell the cells to stop making proteins
Chemical signals tell prokaryotic cells when to divide.

Which description distinguishes the process of meiosis from mitosis?
Unlike mitotic cells, meiotic cells undergo a single division to halve their chromosome number, after which they undergo crossing over to restore their diploid state.
During meiosis cells undergo two divisions to produce haploid cells, allowing for genetic diversity in sexually reproducing organisms.
In meiotic cells, homologous chromosomes remained paired through both rounds of cell division.
Meiotic cells undergo multiple rounds of cell division to produce nearly unlimited diversity.
