Three Structure-Selective Endonucleases Are Essential in the Absence of BLM Helicase in Drosophila
Apoptosis levels are expressed as the average number of cells per imaginal wing disc that stain with antibody to cleaved caspase-3. n = number of discs scored. mus81 and Gen mutant larvae had apoptosis levels indistinguishable from the wild-type control (y w), but mus81 Gen double mutants had significantly increased apoptosis compared to either wild-type or either of the single mutants. *** p<0.0001 (Fisher's exact test).
