What is the name for the area in which these duplicated strands are joined?2.What structures are spindle fibers attached to that help pull the paired chromosomes apart? 3.The chromosomes separate and begin to move to opposite sides of the cell.14.hat is the name for the area in which these duplicated strands are joined? 2.What structures are spindle fibers attached to that help pull the paired chromosomes apart? 3.The chromosomes separate and begin to move to opposite sides of the cell. 14.
Concept 5: Prophase. Chromosomes become visible, the nucleolus disappears, the mitotic spindle forms, and the nuclear envelope disappears. To see prophase animated, click the image. Chromosomes become more coiled and can be viewed under a light microscope. Each duplicated chromosome is seen as a pair of sister chromatids joined by the duplicated but unseparated centromere. The nucleolus disappears during prophase.
