Study Notes
Mitosis Stages
- The key event that marks the beginning of prophase is the condensation of chromosomes.
Anaphase
- Sister chromatids disjoin and are pulled to opposite ends of the cell during anaphase.
- For complete disjunction of sister chromatids to occur, cohesin must be degraded.
Telophase
- Telophase is significant because it is the stage where nuclear envelope reforms around each set of chromosomes.
- During telophase, the process of chromosome uncoiling and reformation of the nuclear envelope occurs.
Sister Chromatid Cohesion
- Cohesin is the protein complex responsible for holding sister chromatids together at their centromere regions.
