Metaphase of Mitosis 1. Homologous chromosomes are independent of one another. Arrange your Triffle chromosomes across the center of the cell. Separate your sister chromatids to form daughter chromosomes. Daughter chromosomes are moved toward opposite poles by the spindle fibers.
Chromatids are flexible.
They do not remain rigid, but rather bend on each side of the centromere as they are dragged through the cytoplasm . The spindle fibers disappear actually, the microtubulin subunits are disassembled. You can remove your spindle fibers from your cells and pretend your chromosomes are going into the extended state. Two new nuclear membranes form, one around each set of daughter chromosomes.
