Study Notes
Stages of Mitosis
- Mitosis is a process where a single cell divides into two identical daughter cells
- Chromosomes are long thin structures visible under a microscope in the nucleus before mitosis
- Before mitosis, chromosomes replicate to form identical sister chromatids joined at the centromere
Stage 1
- Chromosomes condense and become visible
- Nucleus membrane begins to break down
Stage 2
- Chromosomes replicate and become visible
- Nucleus membrane begins to break down
Stage 3
- Chromosomes line up along the cell's equator
- Spindle fibers from each pole of the cell attach to each chromatid at the centromere
Stage 4
- Spindle fibers pull the sister chromatids apart to opposite ends of the cell
Stage 5
- Nuclear membranes reform
- Cytoplasm divides
Stage 6
- Two daughter cells are formed
- Each daughter cell has a complete set of chromosomes (diploid) similar to the parent cell
