SCEs can occur during mitosis or meiosis. Homologous chromosomes are important in the processes of meiosis and mitosis. This segregation process occurs during both mitosis and meiosis. Mitosis and meiosis are types of cell division. In contrast to prokaryotes, eukaryotes reproduce by using mitosis and meiosis. Interphase is the process a cell must go through before mitosis, meiosis, and cytokinesis. Prophase II of meiosis is very similar to prophase of mitosis. In interphase, the cell gets itself ready for mitosis or meiosis. The table below shows the differences between meiosis and mitosis. Therefore, mitotic cell rounding is thought to play a protective role in ensuring accurate mitosis. The S phase starts the sequence of events leading to mitosis and cytokinesis. They regulate cell functions including proliferation, gene expression, differentiation, mitosis, cell survival, and apoptosis. Astral microtubules are a subclass of microtubules which only exist during and around mitosis. Exactly how the nuclear membrane reforms during telophase of mitosis is debated. Binary fission is similar to eukaryote cell reproduction that involves mitosis.
