The first stage of mitosis is called prophase. When you think about it, this makes sense, because the daughter cells must have the same genes as the parent cell. The genetic material, right now in a liquid form called chromatin, copies itself. During interphase, however, something really important happens. This isn’t really a stage of mitosis because this is the time when a cell performs its usual functions. There is also no genetic difference at all between the daughter cells, unless there is some abnormality (such as cancer).īefore mitosis even starts, the cell is said to be in interphase, between mitoses. These product cells are diploid cells, meaning they have the full 46 chromosomes. Mitosis is the process by which a nucleate cell divides into two genetically identical daughter cells.
