Table 2. Genomic mutation rate is unaltered by error-prone TP-DNAP2 variants.
Entries 1–4 are per-base substitution rates of genomic replication in presence of TP-DNAP2 variants, measured using the genomic URA3 locus. Mutagenic TP-DNAP2 variants Y424Q and S370Q cause no statistically significant change in genomic mutation rate, relative to no TP-DNAP2 variant in trans (84% CI overlap method).21 Ranges in parentheses correspond to 95% confidence intervals, determined according to the MSS method.17–19
Entry | TP-DNAP2 in trans | Per-base substitution rate at genomic URA3 locus (x10−10) |
---|---|---|
1 | None | 1.6 (0.8–2.4) |
2 | WT | 2.2 (1.2–3.4) |
3 | Y424Q | 1.8 (1.0–2.9) |
4 | S370Q | 1.8 (1.0–2.8) |
