In mitosis, a cell undergoes a series of steps to divide its nucleus and create two identical daughter cells. The process consists of the following phases:
1. Interphase: The cell prepares for division by growing, carrying out its normal functions, and replicating its DNA.
2. Prophase: The nuclear membrane starts to break down, and the DNA condenses into distinct chromosomes. The spindle apparatus, composed of microtubules, begins to form.
3. Metaphase: The chromosomes align in the middle of the cell, forming a plane called the metaphase plate. The spindle fibers attach to the centromeres of each chromosome.
4. Anaphase: The spindle fibers shorten and pull the sister chromatids apart. The separated chromatids are then referred to as individual chromosomes and are pulled towards opposite poles of the cell.
5. Telophase: The two sets of chromosomes reach opposite ends of the cell, and new nuclear membranes start to form around them. The chromosomes start to decondense.
6. Cytokinesis: The cytoplasm divides into two daughter cells, each containing an identical set of chromosomes. In animal cells, a cleavage furrow forms and deepens until the cytoplasm divides completely. In plant cells, a cell plate forms to separate the cytoplasm, eventually leading to the formation of a new cell wall.
At the end of mitosis, two daughter cells are produced, each containing the same DNA as the original cell. Therefore, the cells have identical DNA and are genetically identical.
