WebIn eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. WebThe cell goes through 4 steps (prophase, metaphase, anaphase, and telophase.) The cells at the end of the process also have the same amount of chromosomes as the parent cell. …

WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes.
