| Abstract: | Separation of chromosomes during mitosis is monitored by a checkpoint that leads to cell-cycle arrest if the chromosomes are not properly attached to the mitotic spindle. Molecular mechanisms controlling this checkpoint have been identified. In addition, loss of this checkpoint has been shown to result in chromosome missegregation in higher eukaryotes and may contribute to the genomic instability observed in human cancers. |
