Simultaneous splitting of the centromeres of each chromosome occur in
1.Anaphase I
2.Anaphase II
3.Metaphase
4.Prophase II
The motion of sister Chromatids toward opposite poles of the cell occurs by
1. | Shortening of microtubules attached to centromere |
2. | Shortening of microtubules attached to kinetochores |
3. | Shortening of microtubules attached to Metaphase plate |
4. | Shortening of microtubules attached to other homologous chromosomes |
