Abstract:
:Broken ends of a budding yeast chromosome exhibit increased mobility, presumably to facilitate repair by recombination. A new study reports that increased mobility reflects the untethering of the broken chromosome, triggered by a DNA damage response that phosphorylates the Cep3 kinetochore protein and weakens the association between the centromere and the spindle pole body.
