Mitosis is a type of cell division in which a diploid cell in the body copies itself and eventually divides into two identical diploid daughter cells. Daughter cells are clones of each other. Chromosomes carry genetic information in a molecule called DNA. A type of cell division called mitosis ensures that, when a cell divides, each new cell produced has the same genetic information.
During mitosis, cells divide to produce two new ones that are exact copies of the original cell. Two daughter cells are produced from the stem cell. Each daughter cell has 46 chromosomes. Mitosis is a process of cell division that results in the production of two daughter cells from a single parent cell.
In the first stage of mitosis, chromosomes become shorter and thicker by the action of tightly winding and packing their components. Each chromosome now exists as a pair of chromatids linked by a centromere. Therefore, the nucleus of the prophase contains twice as many chromosomes as usual. The nuclear envelope disintegrates and each of the centrioles moves to the opposite end of the cell, leaving a wide trail of protein spindle fibers, called microtubules, that run from one centriole to the other.
During the metaphase, each pair of chromatids is attached by their centromeres to the spindle fibers. The stage is completed when all chromatid pairs are aligned in the center of the cell.
