How does the cell divide?

The cell divides through four stages:ProphaseMetaphaseAnaphaseTelophase and CytokinesisBefore prophase the DNA, genetic material of the cell, is coiled and not visible. All that is visible is a dark patch. During prophase this black mess arranges to form the 23 chromosome pairs characteristic for humans. Centrioles, organelles involved in division the align at opposite ends of the cell (poles)In Metaphase, the chromosomes line up at the equator of the cell. The centrioles make microtubules that attach to the middle of the chromosome (centromere)In anaphase the microtubules contract and pull the chromosomes to opposite parts of the cell. In telophase the nuclear envelope begins to re- appear and the chromosomes begin to unwind. Cytokinesis is the final step of the division and consists of the snapping of the cell membrane in two to produce two identical daughter cells
