Question

During meiosis I, the 2 kinetochores of sister chromatids fuse and kinetochore microtubules from one pole of the cell attach to the fused kinetochore. This is important because it ensures that during anaphase I

a.all chromatids in a tetrad are pulled toward the same pole of the cell.
b.non-sister chromatids are pulled toward opposite poles of the cell.
c.non-sister chromatids are pulled toward the same pole of the cell.
d.sister chromatids are pulled toward the same pole of the cell.
e.sister chromatids are pulled toward opposite poles of the cell.
