Mitosis is an important process that helps living things grow and repair themselves. It happens in several steps:
Prophase (about 50-60% of mitosis): The genetic material in the cell gets thicker and turns into chromosomes, which we can see. The outer part of the nucleus breaks down, and tiny fibers called spindle fibers start to form.
Metaphase (approximately 10-15% of mitosis): The chromosomes line up in the middle of the cell. They are attached to the spindle fibers, like strings on a puppet.
Anaphase (around 10% of mitosis): The sister chromatids, which are copies of chromosomes, pull apart and move to opposite sides of the cell.
Telophase (about 20-30% of mitosis): The chromosomes start to relax and turn back into their original form. New nuclear envelopes form around them, and the cell gets ready to split in two.
This whole process usually takes about 30 minutes in human cells. Mitosis is really important because it helps keep our bodies healthy by allowing cells to divide properly.
