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
