Mitosis is an important process that helps cells divide and create new cells. It happens in several main stages:
Prophase: The DNA inside the cell starts to bunch up and form structures called chromosomes. At this time, the nuclear envelope (the layer that protects the nucleus) breaks down. Humans have 46 chromosomes, arranged in 23 pairs.
Metaphase: The chromosomes line up in the middle of the cell. They connect to tiny fibers called spindle fibers at a point known as the centromere.
Anaphase: The sister chromatids (the two halves of each chromosome) are pulled apart to opposite sides of the cell. This ensures that when the cell divides, each new cell will have the same set of chromosomes.
Telophase: New nuclear envelopes form around each set of chromosomes. Then, the cell splits into two identical daughter cells through a process called cytokinesis.
Mitosis is really important for growing and healing our bodies. It helps repair tissues and makes sure we have new cells when we need them.
