WebAug 19, 2024 · Both processes involve the division of a diploid cell, or a cell containing two sets of chromosomes (one chromosome donated from each parent). In mitosis, the genetic material ( DNA) in a cell is duplicated and divided equally between two cells. The dividing cell goes through an ordered series of events called the cell cycle.
