- Mitosis
- Prophase
- nucleus/nuclear membrane
- After replication, the chromosomes coil up, contract and become visible
- Therefore 2 chromotids joined at the centromere
- Metaphase
- Nuclear membrane breaks down
- Spindle forms across the cell, formed of microtubules. The cytoskeleton controls this
- Chromosomes attach to the spindle fibres in the middle of the cell
- Anaphase
- The centromeres split and each chromosome separate
- They move along to opposite ends of the cell
- Telephase
- Chromotids join together at ends of cell
- Nuclear membrane develops
- Cytokinesis
- New cell membrane develops
- Chromosomes uncoil
- Plant cells do not have centioles but they do form a spindle
- Chromotid -single chromosome
- Cells need to divide copy all the DNA in each exactly into the daughter cells. Each all then has a period of producing the proteins needed. Before each daughter cell then undergo mitosis again. This is called the cell cycle
- Plant cells do not furrow during cytokinesis, they form a rigid plate in the centre of the cell where a new cell wall forms
- Prophase
