3.24c Mitosis

• When a cell first breaks down it shows that it is entering the process of mitosis and cell division.
• Chromosomes become visible as "chromotids" in a pair after the breakdown of the membrane.
• As cell division carries on fibres form and each end of the cells.
• Chromotids line up in the middle of the cell and are pulled apart by fibres.
• The nucleus forms around the chromosomes at each end causing two nuclies.
