Which of the following experimental observations (some real, some contrived) would not be consistent with our current understanding of cytokinesis?

#Unit 2. Cellular Organization

  1. Anti-myosin antibodies injected in a dividing cell cause cytokinesis to stop.

  2. When the myosin II gene is mutated, cells undergo nuclear division, but not cytokinesis.

  3. Anti-actin antibodies injected into dividing cells have no effect on cytokinesis.

  4. Actin filaments seen in micrographs are aligned parallel to the cleavage furrow.
