A central part of the machinery of cell division is the spindle. The creation and operation of this structure seem to require a component of the cell's infrastructure not previously associated with it.

A shocking thing has happened in the world of the cytoskeleton, the complex of proteins responsible for cell shape and movement. One of the most important structures it forms is the spindle, which ensures the faithful delivery of replicated chromosomes to daughter cells following cell division.
