title: Traction fibres in chromosome movement: the pros and cons.
abstract: The current discussion on the mechanism of chromosome movement in anaphase is dominated by a new hypothesis assuming active movement of the chromosome along stationary kinetochore microtubules. The aim of this article is to call attention to several older as well as to more recent observations on spindle structural dynamics and microtubule rearrangements which, in the author's opinion, cannot be explained by the new model. In fact, the observations seem to be more consistent with the classical concept of a traction fibre. For this reason, these observations should not be disregarded.
