Detailed explanation-1: -During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell. Following prometaphase, metaphase begins. At the start of metaphase, the microtubules arrange the chromosomes in a line along the equator of the cell, known as the metaphase plate (Figure 3b).

Detailed explanation-2: -Anaphase: During anaphase, the centromere splits, allowing the sister chromatids to separate. The kinetochore spindle fibers shorten, allowing for 46 of the newly-freed chromatids to be dragged to one end of the cell and the remaining 46 chromatids to be dragged to the opposite end of the cell.

Detailed explanation-3: -In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
