Explanation
I. Spindle microtubules that extends from the two poles of a dividing cell are called polar fibres II. A centromere that connects two identical copies of single chromosome. These two copies are called sister chromatids III. In ‘X’ phase, the paired chromosomes separate and begin moving to opposite ends of the cell. This ‘X’ phase is called anaphase
