Because of your expert knowledge of cell division, you and your colleagues have been hired by an established online, user-written encyclopedia as content editors. Your job is to read entries submitted on topics about cell division and edit them for accuracy.
Mitosis is a dynamic process. For purposes of description it is typically broken down into phases which are briefly described below:
Prophase: Chromosomes condense; nuclear membrane breaks down; mitotic spindle begins to form; kinetochores begin to migrate to demarcate the two poles.
Prometaphase: Spindle apparatus completes formation; sister chromatids are attached to spindle fibers via polar microtubules.
Metaphase: Chromosomes are aligned at the center of the cell.
Anaphase: Homologous chromosomes separate and migrate to opposite poles.
Telophase: Nuclear membrane forms around each set of chromosomes; chromosomes decondense.
Although not a part of mitosis, the division of the cytoplasm, called cytokinesis, typically occurs after anaphase.
