Which of the following events is characteristic of the transition from metaphase to anaphase in mitosis?
- A.Splitting of centromeres and separation of sister chromatids
- B.Condensation of chromatin into chromosomes
- C.Formation of the nuclear envelope around daughter nuclei
- D.Alignment of chromosomes at the equatorial plate
Show correct answer & step-by-step solution
Correct answer: A — Splitting of centromeres and separation of sister chromatids
Solution
- Metaphase is characterized by chromosomes aligned at the metaphase plate.
- The transition to anaphase is triggered by the splitting of centromeres.
- This action separates the sister chromatids.
- The separated chromatids then move toward opposite poles.
- Hence the answer is (A).
