Mitosis And Cytokinesis

Mitosis is a form of cell division where a cell's genetic material is partitioned between two daughter cells. 

First, during prophase, nucleic chromatin condenses into x-shaped chromosomes composed of sister chromatid pairs attached at centromere junctions.

Concurrently, the centrosomes migrate to opposite cell sides. As they do so, microtubule rods begin to grow from each, forming a web-like spindle apparatus.

Next, the nuclear envelope dissolves during prometaphase and the protein structures, termed  kinetochores, appear on both sides of the centromeres, one for every chromatin.

Once these kinetochores form, extending interior microtubules fasten to them, with each sister chromatid being tethered to a different cell pole.

In  metaphase, the spindle apparatus rearranges the chromosomes so that they are oriented in a fixed row along the cell's equator.

With anaphase, kinetochore afixed microtubules shorten and sister chromatids are dragged apart. These and other microtubule dynamics also elongate the cell.

During telophase, the spindle apparatus disbands, chromatids loosen, and nuclear envelopes are reformed.

Finally, the cell is cytoplasmically divided by cytokinesis, forming a pa
