Table of the mean frequencies of sequence variation (in ORFs, introns, 5′UTRs and 3′UTRs) per nucleotide for the oxidative and reductive phases.

Standard deviations (SD), p- values for the two-tailed Wilcoxon rank sum test, and frequency of sequence variation ratios between the oxidative and reductive phases, and their 95% confidence intervals (C.I. 95%) for S. cerevisiae over the time of divergence for 63 strains. Ox (1–4) designates the four time points of the oxidative phase, and Red (5–12) designates the eight time points of the reductive phase in the redox cycle.
