Mitosis is a method of cell division in which a cell divides and produces identical copies of itself.The primary mechanism by which organisms generate new cells is through cell division. During this process, a single “parent” cell will divide and produce identical "daughter" cells. In this way, the parent cell is able to pass on its genetic material to each of its daughter cells. First, however, the cells must duplicate their DNA. Mitosis is the process by which a cell segregates its duplicated DNA, ultimately dividing its nucleus into two.
