Abstract:
:Micronucleation of missegregated chromatin can lead to substantial chromosome rearrangements via chromothripsis. However, the molecular details of micronucleus-based chromothripsis are still unclear. Now, an elegant system that specifically induces missegregation of the Y chromosome provides insight into this process, including a role for non-homologous end joining.

Members of the Rho-family of GTPases are crucial regulators of this process and assembly of the contractile ring depends on local activation of Rho signalling.
