Mitosis
- Prophase
- Metaphase
- Anaphase
- Telophase
Prophase
- Separates duplicated genetic material
- Already double amount of chromosomes due to S-phase
- Chromatin condense (chromosomes thicker & shorter) and become visible
- Nucleolus disperse
- Nuclear envelope breaks
- Spindle fibres form
Metaphase
- Genetic material into two separate daughter cells
- Chromosomes align at centre of cell
- Spindle fibres from each pole attach to the centromere of the chromosomes
Anaphase
- Spindle fibres shorten
- Chromosomes are split by the the centromere and the sister chromatids are pulled to opposite poles of cell
Telophase
- Spindle fibres dismantle
- Nuclear envelope reforms around each daughter nucleus
- Nucleoli appear in each daughter nucleus
- Now have 2 GENETICALLY IDENTICAL daughter cells
