mitosis. In this module you will learn about mitosis. Mitosis is a process of cell division that makes possible regeneration of body parts. To elaborate mitosis is the separation of nuclear chromosomes into two identical dot-on nuclei. It is divided into four key phases, row phase, metaphase, inner phase and tealophase. An additional phase called cytokine necessarily occurs after the complete nuclear division. Before a dividing cell enters mitosis, it undergoes a period of growth and rest. This period is called interface. In interface, the genetic material of a cell increases. Pro phase, during pro phase, the chromatin condensers and becomes short and thick to form chromosomes. Each chromosome has two sister chromatives joined together at the centromia. The nucleus disappears and the nuclear membrane starts to break down. The central zones, each with a pair of centrioles, move apart to the opposite pose forming a spindle between them. Metaphase, during metaphase, microtubules of the spindle interact with chromosomes. This causes the chromosomes to move and align along the middle of the cell or the equatorial plate. Sister chromatives are held at the centromia, confirming the presence of protein structures called kinetocore at the surface. The kinetocore holds the chromosomes and attaches them to the spindle. Anaphase, during inner phase, the sister chromatives separate at the kinetocore and the daughter chromosomes along with the divided centromia, move towards the opposite pose as the microtubule shortens. The pose of the spindle also move apart and help to separate the chromosomes. As the chromosomes separate completely into two sets, one at each pole, inner phase is considered complete. Teelo phase. During teelo phase, the daughter chromosomes arrive at the pole and the chromatin starts to decoyle. Also, the nuclei reform along with nucleolide. This triggers the reformation of the nuclear membrane. Sito kinesses Sito kinesses is the partition of the cytoplasm. In animals, a cleavage furrow fears in the plasma membrane which deepens and divides the cytoplasm into two daughter cells, each containing a nucleus. In plants, new cell wall formation is triggered at the center of the cell by the formation of a cell plate. The cell plate grows outwards till it needs the existing wall, resulting in two daughter cells. In this module you have learnt, mitosis is the process of separation of nuclear chromosomes into two identical daughter nuclei. Mitosis involves four key phases, pro phase, metaphase, anaphase, and teelo phase. In pro phase, the chromatin condensers and becomes short and thick to form the chromosomes. In metaphase, micro tubules of the spindle interact with the chromosomes. In anaphase, the sister chromatids separate out at the centromia and move towards the opposite poles as the micro tubule becomes shorter. In teelo phase, daughter chromosomes arrive at the pole and chromatin starts to decoyle, followed by the reformation of nuclear lie and nuclear.
