Web9 dec. 2016 · Meiosis occurs in two distinct divisions, with different phases in each. Phases of Meiosis Before meiosis, the DNA is replicated, as in … WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
