WebJun 8, 2024 · Figure 10.2 A. 1: The Stages of Interphase and the Cell Cycle: The cell cycle consists of interphase and the mitotic phase. During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. WebIn each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Meiosis I Before entering meiosis I, a cell must first go through interphase. As in mitosis, the cell grows during G _1 1 phase, copies all of its chromosomes during S phase, and prepares for division during G _2 2 phase.
