Cell Division - Mitosis: its Stages (GCSE Biology)
Mitosis: Its Stages
Mitosis in More Detail
There are also different stages in mitosis and each stage has a specific name. These include the following:
1. Prophase
- Chromosomes condense. They get shorter and the nucleus membrane breaks down – this releases the chromosome into the cytoplasm.
2. Metaphase
- Chromosomes line up on the equator. Chromosomes line up on the equator (middle) of the cell.
3. Anaphase
- Chromosomes are pulled to opposite poles of the cell. The separate ends of the cells are called the poles. The chromosomes are pulled to the poles by spindle fibres.
4. Telophase
- Two new nuclei form. New membranes are built around these chromosomes, so they become new nuclei. This means that the nucleus has divided into two.
Now the cell will divide into 2 via the process of cytokinesis.
