Table 1.

High proportion of pol2rc-ΔN cells cannot form or have difficulty forming daughter cell buds compared to wild-type cells^a

Strain	Percent of cells that divided the indicated number of times: (95% confidence intervalb)
	Zero	One to two	More than three
wild type	2 (0.5–7)	1 (0.2–5)	97 (91.5–99)
pol2rc-ΔN	8 (4–15)	16 (10–24)	76 (65–82)

^aThe experiment design is described in Materials and Methods. The photo of the final appearance of the grids is in Supplementary Figure S8.

^bThe 95% confidence interval was calculated using the Score method (Breusch and Pagan 1980).

Association between wild type or pol2rc-ΔN and how many times cells divided is statistically significant, estimated by Pearson’s χ² statistic in a contingency table (χ² =18.9, P = 0.000079).
