The apoptotic suicide programme involves fragmentation of nucleosomal DNA. In the July 5 Nature, two groups report identification of a mitochondrial nuclease that induces DNA degradation associated with apoptosis in both worms and mammals. Parrish et al. performed a genetic screen in Caenorhabditis elegans to search for suppressors of an activated cell-death protease (CED-3) mutant (Nature 2001, 412:90-94). After screening 3,000 mutagenized haploid genomes, they identified an apoptosis-related g
