			A 4D movie showing the DNA bead-induced ectopic polar body extrusion during meiosis II. The DNA beads (shown in blue) were injected at 10 O'clock position. Microtubules were labeled by microinjection of rhodamine conjugated tubulin. Note that the DNA bead spindle underwent rotation from horizontal to vertical position and the DNA beads were kept in the eggs after ectopic polar body extrusion. Maternal chromosomes are out of the z-sections.
