Outline: Anaphase in Cell Division

• Introduction

  • Description of anaphase in cell division.

  • Chromosomes split at the metaphase plate.

• Key Events in Anaphase

  • Centromeres split.

  • Chromatids separate.

  • Daughter chromatids become daughter chromosomes.

• Chromatid Movement

  • Migration towards opposite poles.

  • Centromeres directed towards poles.

  • Arms of chromosomes trail behind.

• Characteristics of Anaphase

  • Simultaneous splitting of chromosomes.

  • Directional movement of chromatids.

• Conclusion

  • Recap of anaphase events.

  • Importance of proper chromosome separation for cell division.

At the onset of anaphase, each chromosome arranged at themetaphase plate is split simultaneously and the two daughterchromatids, now referred to as daughter chromosomes ofthe future daughter nuclei, begin their migration towardsthe two opposite poles. As each chromosome moves awayfrom the equatorial plate, the centromere of each chromosomeremains directed towards the pole and hence at the leadingedge, with the arms of the chromosome trailing behind(Figure 10.2 c). Thus, anaphase stage is characterised by he following key events:Centromeres split and chromatids separate.Chromatids move to opposite poles
