Understand the process of mitosis, which is the division of a single cell into two genetically identical daughter cells. Mitosis consists of several phases: prophase, metaphase, anaphase, and telophase.
Recall that during prophase, the chromosomes condense and become visible, and the nuclear envelope begins to break down.
In metaphase, the chromosomes align along the metaphase plate, which is an imaginary line equidistant from the two centrosome poles of the cell. This alignment ensures that each daughter cell will receive an identical set of chromosomes.
During anaphase, the sister chromatids are pulled apart by the spindle fibers and move toward opposite poles of the cell.
Finally, in telophase, the chromosomes begin to de-condense, and the nuclear envelope re-forms around each set of chromosomes, completing the process of mitosis.
