What happens in each phase of mitosis.

Answer 1

1. Prophase:
- Chromosomes condense and become visible
- Nuclear membrane dissolves
- Spindle fibers form and attach to the centromeres of the chromosomes
- Centrioles move to opposite ends of the cell

2. Metaphase:
- Chromosomes line up along the metaphase plate in the middle of the cell
- Spindle fibers attach to the centromeres of the chromosomes

3. Anaphase:
- Sister chromatids separate and move towards opposite ends of the cell
- Spindle fibers shorten, pulling the chromatids apart

4. Telophase:
- Chromatids arrive at the opposite poles of the cell
- New nuclear membranes form around each set of chromosomes
- Chromosomes begin to de-condense
- Spindle fibers disappear

5. Cytokinesis:
- The cell membrane pinches in at the center of the cell, dividing the cytoplasm into two daughter cells
- Each daughter cell receives a complete set of chromosomes

Overall, mitosis is a process of cell division that results in two genetically identical daughter cells. It ensures that each daughter cell receives a complete set of chromosomes.
