G 1 a period of growth and synthesis of new cell parts. Condensation of chromatin into visible sister chromatids with centromeres. Microtubules disassemble and create spindles. Centrioles, if present, separate and go to poles. Nuclear envelope has disintegrated.
Chromatids line up at the equator of the cell with sister chromatids at right angles to the spindle.
Sister chromatids separate. The spindle apparatus disappears. Nuclear envelope reappears. Cytokinesis Cytokinesis devides up the cytoplasm and make two new cells. It occurs during late anaphase and throughout telophase.
