cell division, diversity and organisation

• the purpose of mitosis and the cell cycle is to produce identical daughter cells for growth and asexual reproduction of cells.
• All cells produced via mitosis are genetically ientical, therefore mitosis does not give rise to genetic variation.
• What are the three stages of the cell cycle?

  Mitosis

  Cytokinesis

  Interphase
• Mitosis - Mitosis is a form of cell division that produces identical cells.
• What are the four stages of mitosis?

  Prophase

  Metaphase

  Anaphase

  Telophase
• Cytokinesis - during cytokinesis, the parent and replicated organelles move to opposite sides of the cell and the cytoplasm divides thus producing two daughter cells.
• interphase - during this stage, the cell grows and prepares to divide. chromosomes and some organelles are replicated, chromosomes also begin to condense.

  
• during prophase, the nuclear envelope breaks down and subsequently disappears. the chromosomes condense and the centrioles move to opposite poles of the cell for the purpose of spindle formation.
• in the anaphase, the sister chromatids are separated.

  
• during the telophase, the nuclear envelope reforms, creating two daughter cells. the spindle is broken down and subsequently dissapears. The chromosomes uncoil
