•Part of the ‘cell cycle’
•Existing cell divides into two new ones (Mother cell –> 2 Daughter cells)
•The daughter cells are identical to the parent cell.
•Mitosis is associated with cell growth and repair of tissue.
*During interphase –> prophase, the chromosomes become thicker and shorter.
This is because of the coiling of chromosomes. When a cell divides, the chromosomes have to be wound up. To do this, the beaded coils form tight chromatin coils called chromatin fibres. Then these form loops called looped domains. These looped domains coil and fold even more to form the characteristic of chromosome you cell during cell division. This is important step of the mitosis so they do not get tangled as they move into different cells.
