Mitosis
Mitosis is a type of cell division in which a mother cell divides to form two identical daughter cells.
The process has four stages.
It begins with prophase, where the thin thread-like DNA in the nucleus, called chromatin, coils tightly to form chromosomes.
Each chromosome consists of two identical copies known as sister chromatids, joined at a central region called the centromere.
As the chromosomes form, the nuclear envelope surrounding the nucleus breaks down, and thin fibers called spindle fibers begin developing from the centrosomes.
Next is metaphase. Here, the chromosomes align in the center of the cell, and the spindle fibers attach to the centromere of each chromosome.
During anaphase, the spindle fibers pull the sister chromatids to opposite ends of the cell, ensuring that each side gets an identical set of chromosomes.
In telophase, two new nuclei form around the separated chromosomes, and the spindle fibers dissolve, completing the division of chromosomes.
After this, the cell begins to split through a process called cytokinesis. Here, the cytoplasm and its organelles are distributed between the two cells.
