Key Stages of Mitosis:
Prophase:
The DNA, called chromatin, gets thicker and turns into chromosomes. Humans have 46 chromosomes.
The nuclear membrane, which surrounds the nucleus, breaks apart.
Metaphase:
The chromosomes line up in the middle of the cell.
Special fibers, known as spindle fibers, connect to the center of each chromosome.
Anaphase:
The sister chromatids, which are the two halves of each chromosome, pull apart and move to opposite sides of the cell.
Telophase:
New nuclear membranes form around each group of chromosomes, helping to create two new nuclei.
Cytokinesis:
The cell’s cytoplasm splits, leading to the creation of two identical daughter cells.
Differences from Meiosis:
Mitosis:
This process makes 2 identical cells. It helps our bodies grow and repair themselves.
Meiosis:
This process creates 4 unique cells. These cells are used for reproduction.
Meiosis involves matching up chromosomes and goes through two rounds of division, called Meiosis I and Meiosis II.
