Climbing up a cliff while the rope unravels underneath
your fingers does not sound like a well-planned adven-
ture. Yet chromosomes face a similar challenge during
each cell division. Their alignment and accurate segre-
gation depends on staying attached to the assembling
and disassembling tips of microtubule fibers. This cou-
pling is mediated by kinetochores, intricate machines
that attach chromosomes to an ever-changing microtu-
bule substrate. Two models for kinetochore-microtubule
