About the Cover
Cover: Polar body of a syncytial Drosophila embryo showing condensed chromosomes (blue), and localization of the spindle checkpoint protein BubR1 (red) and the centromeric marker CID (green). Loss of BubR1 results in failure to arrest, causing chromosomes to undergo cycles of DNA replication and condensation in synchrony with abnormal syncytial divisions. See article by Pérez-Mongiovi et al. on p. 4509.
