Meiosis: Prophase I - Chromosomes become visible. The nuclear envelope breaks down. Crossingover occurs. Metaphase I - Pairs of homologous chromosomes move to the equator of the cell. Anaphase I - Homologous chromosomes move to opposite poles of the cell. Telophase I and cytokinesis - Chromosomes gather at the poles of the cell. Cytoplasm divides. Prophase II - A new spindle forms around the chromosomes. Metaphas II - Chromosomes line up at the equator. Anaphase II - Centromeres divide. Chromatids (now called chromosomes) move to opposite poles of the cell. Telophase II and cytokinesis - A nuclear envelope forms around each set of chromosomes. The cytoplasm divides. Mitosis: Prophase - Chromosomes become visible. The nuclear envelope breaks down. Spindle forms. Metaphase - Chromosomes line up along equator. Anaphase - Centromeres divide. Chromatids (now called chromosomes) move toward opposite poles. Telophase - Nuclear envelope forms at each pole. Chromosomes uncoil. Spindle dissolves. Cytokinesis begins.
