Mitosis is a process of cell division that ensures the accurate distribution of replicated chromosomes to two daughter cells.
It consists of several phases: prophase, metaphase, anaphase, and telophase. During prophase, chromatin (a complex of DNA and proteins) condenses into visible chromosomes. The nuclear envelope begins to break down, and the mitotic spindle, composed of microtubules, starts to form.
In metaphase, the condensed chromosomes align at the cell's equator, known as the metaphase plate. The spindle fibers attach to the centromeres of the chromosomes, ensuring they are positioned correctly for separation.
