WebThe mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and move into two new, identical daughter cells. The first portion of the mitotic phase is called karyokinesis, or nuclear division. WebThe spindle fibers ensure that sister chromatids will separate and go to different daughter cells when the cell divides. Chromosomes, consisting of sister chromatids, line up at the equator or middle of the cell during metaphase. Anaphase During anaphase, sister chromatids separate and the centromeres divide. Webnot undergoing cell division. Spindle fibers which will move the chromosomes begin to form. 3. Spindle fibers attach to the chromosomes and line the chromosomes up in the middle of the cell. 4.
