Mitosis PMET

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
