In most cells, the DNA damage checkpoint delays cell division when replication is stalled by DNA damage. In early Caenorhabditis elegans embryos, however, the checkpoint responds to developmental signals that control the timing of cell division, and checkpoint activation by nondevelopmental inputs disrupts cell cycle timing and causes embryonic lethality.(More)
Faithful chromosome segregation during meiosis I depends on the establishment of a crossover between homologous chromosomes. This requires induction of DNA double-strand breaks (DSBs), alignment of homologs, homolog association by synapsis, and repair of DSBs via homologous recombination. The success of these events requires coordination between chromosomal(More)
Repetitive sequences in Caenorhabditis elegans are interspersed along the holocentric chromosomes. We have physically mapped some of these repetitive families and found that, although the distribution of members of each family is relatively even along the chromosomes, members of more than one family tend to cluster in some locations. We compared the(More)
