DESCRIPTION
All the notes on the stages of Mitosis
Citation preview
Interphase1. DNA is stretched
out and is being read by the cell
2. Chromosomes replicate.
3. Chromosomes cannot be seen
Nucleus
Cell Membrane
Prophase
1. Nucleus starts to disappear.
2. Sister Chromatids pair up to form chromosomes, which now can be seen.
3. Centrioles duplicate and move to the poles
Centromere
Metaphase1. Spindle Fibers
appear.
2. Chromosomes line up along the middle of the spindle.
3. Fibers attach to centromere.
Spindle Fibers
Anaphase
1. Spindle fibers pull the chromosomes apart
2. Chromatids are pulled to the centrioles.
Telophase
1. Spindle Fibers and centrioles disappear.
2. Nucleus reappears around each of the new sets of chromosomes.
3. Cell starts to form a break at the middle and starts to pinch in at the sides.
Telophase (continued)
4. Cell continues to split at the mid-line forming two cells that are completely identical. This cell splitting is called cytokinesis
