LRV conceived of testing the effects of Pif1p overexpression on viability of yku and cdc13–1 cells. LRV, JAP, and VAZ conceived, designed, and analyzed the experiments (except for the experiments in Figures 1D and S1) and wrote the paper. LRV, JAP, BRT, JAB, and MTO performed the experiments. BRT, JAB, and DPT designed, conducted, and analyzed the experiments presented in Figures 1D and S1.
