Mitosis
Mitosis is one of biology's more complex processes and the process that is responsible for cell division in humans and all eukaryotes.
Mitosis is broken down into four phases: Prophase, Metaphase, Anaphase, and Telophase. Below, I will explain in detail what happens during each of these phases.
During mitosis, one cell divides itself to produce two daughter cells. Each of these cells are genetically identical to each other and so contain the same DNA.

Steps of Mitosis
There are four separate steps of Mitosis:
- Prophase: The cell's nuclear membrane disappears and the chromatin coils into tightly packed structures called chromosomes. Also, centrioles form and spindle fibers stretch across the cell.
- Metaphase: Chromosomes move to the center of the cell and live up along the cell's midline.
- Anaphase: Chromosomes begin to be pulled across to opposite sides of the cell by the the spindle fibers.
- Telophase: The Chromosomes finish moving to opposite ends of the cell. The centrioles and spindle fibers begin to disappear and the nuclear membrane re-forms.
- Cytokinesis: During this step, the cell's cytoplasm divides and the two cells pinch off from each other in the case of animal cells or form a cell plate between them in the case of plant cells.
