Describe the main stages of cell division

Interphage: G1 phase = Increased metabolic reactions, protein synthesis, organelle production, cell checks whether to divide or not S phase = DNA replication --> creation of sister chromatids G2 phase = Further protein synthesis and organelle production, formation of centrosomes M phase: Prophage: chromatid condenses, mitotic spindle formation, nuclear envelope breaks down Metaphase: microtubules have bound to the kinetochore found at the centromere of each chromosome, chromosomes are lined up at the equator of the cell Anaphase : sister chromatids seperate and are pulled at the opposite ends of the cell. Each is now its own chromosome Telophase :mitotic spindle is broken down, 2 new nuclei form - one for each set of chromosomes, nuclear membranes reform, chromosomes begin to decondense Cytokinesis: division of the cytoplasm to form two new cells,may start in either anaphase or telophase
