| Describe Interphase. | Stage 0 Cell is actively synthesising proteins. Chromosomes invisible. Prior to mitosis, DNA replicates. |
| Describe Prophase. | Stage 1 Chromosomes become visible. Nuclear envelope disintegrates. Nucleolus disappears. |
| Describe Metaphase. | Stage 2 Spindle forms. Chromosomes line up on the centre of the cell. |
| Describe Anaphase. | Stage 3 Spindle fibres attached to chromatids contract. Chromatids are pulled towards poles. |
| Describe Telophase. | Stage 4 Chromosomes reach poles and become indistinct. Nuclear envelope reforms. Nucleolus reforms. Spindle disintegrates. |
| Define Mitosis | Mitosis produces two daughter cells that have the same number of chromosomes as the parent cell and each other. |
