Mitosis is a process of cellular division. While the name mitosis is very similar to the word meiosis, the two processes produce very different cells. Meiosis produces gametes that are haploid cells, because those are the cells necessary for sexual reproduction. Mitosis produces cellular clones with a complete set of chromosomes.
The entire cell cycle begins with interphase, and interphase contains Gap 1, Synthesis Phase, and Gap 2. The two Gap phases are mainly growth phases. Because mitosis follows interphase, and because mitosis will finish with cellular division, a cell needs to replicate its entire genetic compliment. This will happen during Synthesis Phase.
Upon completion of interphase, the cell begins mitosis. Mitosis is a four-step process that begins with prophase. Prophase is the longest step of mitosis, and it is the phase in which the nuclear membrane breaks down and the centrioles migrate to opposite sides of the cell. Metaphase is next, and it has the sister chromatids lined up across the cell's equator. The spindle fibers will attach to the sister chromatids and begin pulling them apart. This pulling of the chromosomes to opposite sides of the cell is anaphase.
Telophase follows, and it is during this phase that the nuclear membranes will reform around the now-separated DNA. The cell membrane will begin to pinch inward in order to divide the cell in two, and the complete separation occurs during cytokinesis. What has been produced are two identical cells that are each diploid. They are called "daughter cells," and they are identical to the original "parent cell."
