FIG 5.

Topoisomerase 1 defects can suppress the slow-growth phenotype and aberrant morphology phenotype of selected rnh203Δ double mutants. (A) Doubling times, with error bars indicating the standard deviations, are presented for the indicated single, double, and triple mutant strains. (B) The budding index was measured to determine the percentage of cells in each phase of the cell cycle and the percentage of cells with an aberrant morphology phenotype. Representative examples are presented as histograms, with error bars indicating the standard deviations. (C) Summary of the budding index data for mutant strains and controls.
