Study Notes
Mitosis Stages
-
Prophase:
- Chromosomes condense (formed from two chromatids connected by a centromere)
- Nuclear membrane breaks down
- Centrioles move to opposite ends of the cell
- Spindle fibers (made of microtubules) begin to form.
-
Metaphase:
- Spindle fibers move chromosomes to the center of the cell.
-
Anaphase:
- Chromatics of each chromosome separate at the centromere
- Spindle fibers pull the separated chromatids (now chromosomes) towards opposite ends of the cell.
-
Telophase:
- Spindle fibers disappear
- Chromosomes return to chromatin (less condensed form)
- Nuclear envelope and nucleolus reform.
