Key Concepts

Mitosis

• Mitosis is the process of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
• It is crucial for growth, development, and tissue repair.

Stages of Mitosis

1. Prophase

   • Chromosomes condense and become visible.
   • The nuclear envelope begins to break down.
   • Spindle fibers start to form.

2. Metaphase

   • Chromosomes align at the cell equator.
   • Spindle fibers attach to the centromeres of the chromosomes.

3. Anaphase

   • Sister chromatids are pulled apart to opposite poles of the cell.

4. Telophase

   • Chromatids reach the poles and begin decondensing.
   • A new nuclear envelope forms around each set of chromosomes.

Cytokinesis

• Cytokinesis is the division of the cytoplasm to form two separate daughter cells after mitosis.
• In animal cells, this occurs through a process called cleavage, forming a cleavage furrow that pinches the cell into two.

Importance of Mitosis and Cytokinesis

• Ensures genetic consistency across cells.
• Enables growth and repair of tissues.
