WebDefinition of Mitosis. Mitosis is the division of a single cell nucleus into two daughter nuclei. This process results in two genetically identical cells with the same number of chromosomes as the parent cell. Mitosis is a complex process, comprised of four steps: prophase, metaphase, anaphase, and telophase. WebProphase It is the first phase of mitosis, the DNA is condensed from the loose state (chromatin). The chromatin, during Prophase, gets packaged tightly by special proteins called histones. Centrioles appear on the two sides of the cell.
