Explain the process of mitosis in a tissue culture for normal cells.

Mitosis is a process cell division, where one cell divides into two identical cells. Mitosis consists of four phases - prophase, metaphase, anaphase, telophase and cytokinesis. 1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up. 2. Metaphase: Chromosomes line up at the centre of the cell. 3. Anaphase: The sister chromatides separate from each other to the oposite sides of the cells. 4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cell.
