The cell cycle has two major phases: interphase and the mitotic phase ( Figure 10.5). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell cytoplasm is typically partitioned by a third process of the cell cycle called cytokinesis. We should note, however, that interphase and mitosis (karyokinesis) may take place without cytokinesis, in which case cells with multiple nuclei (multinucleate cells) are produced.įigure 10.5 The cell cycle in multicellular organisms consists of interphase and the mitotic phase. Interphase is followed by the mitotic phase.ĭuring interphase, the cell grows and the nuclear DNA is duplicated. During the mitotic phase, the duplicated chromosomes are segregated and distributed into daughter nuclei. Following mitosis, the cytoplasm is usually divided as well by cytokinesis, resulting in two genetically identical daughter cells.
