Mitosis

• Mitosis is a process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell.
• Cells need to divide in order to grow and repair damaged tissues.
• Mitosis:

  A) Interphase

  B) Prophase

  C) prometaphase

  D) Metaphase

  E) Anaphase

  F) Telophase

  G) Cytokinesis

  
• Interphase: chromosomes duplicate, and the copies remain attached to each other.

  
• Prophase: In the nucleus, chromosomes condense and become visible. In the cytoplasm the spindle forms.

  
• Prometaphase: The nuclear membrane breaks apart, and the spindle starts to interact with the chromosomes.

  
• Metaphase: The copied chromosomes align in the middle of the spindle.

  
• Anaphase: Chromosomes separate into two genetically identical groups and move to opposite ends of the spindle.

  
• Telophase: Nuclear membranes form around each of the two sets of chromosomes, the chromosomes begin to spread out, and the spindle begins to break down.

  
• Cytokinesis: The cell splits into two daughter cells each with the same number of chromosomes as the parent. In humans, cells have two copies of 23 chromosomes and are called diploid.

  
• A cell's genetic material needs to be copied before it divides by mitosis. To make an identical cell that has 46 chromosomes just like the original, you need to duplicate the chromosomes/ genetic material first before splitting the cell.
• In animals, cytokinesis takes place through the formation of a depression in the plasma membrane, whereas cytokinesis takes place through the formation of a cell wall.
