  Cell Division
• Mitosis is the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division. Mitosis is generally followed by equal division of the cell's content into two daughter cells that have identical genomes.
• The first person credited with the discovery and detailed study of mitosis was the German biologist Walther Flemming (1843–1905).
• Flemming described the whole process of mitosis, from chromosome doubling to their even partitioning into the two resulting cells, in a book published in 1882
• Interphase


  1. G1 (Gap 1)

  2. S (Synthesis)

  3. G2 (Gap 2)
• Interphase is the longest phase of the cell cycle, where the cell grows, carries out its normal functions, and prepares for cell division.
• Interphase is not a stage of mitosis. It is the period between cell divisions when the cell grows and prepares for cell division.
• Prophase


  The first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
• Metaphase


  A stage during the process of cell division (mitosis or meiosis) where the nucleus dissolves and the cell's chromosomes condense and move together, aligning in the center of the dividing cell.
• Anaphase


  The sister chromatids separate and are pulled to opposite poles of the cell by the mitotic spindle, resulting in two identical sets of chromosomes.
• Telophase

  The mitotic spindle disassembles, and the nuclear envelope reforms around the separated chromosomes. The chromosomes begin to decondense, and the cell prepares for cytokinesis.
• Cytokinesis

  The cell membrane pinches inward, dividing the cytoplasm and organelles into two daughter cells. The daughter cells are genetically identical to the parent cell.
