Fig. 2. Mutagenesis in wild-type cells is restricted to the vicinity of the broken replication fork.
(A) Positions of URA3 reporter genes with respect to broken forks. (B) Diagram of possible recombination template switches leading to gene conversion. (C and D) Median 5-FOAR break–induced (+FLP) and spontaneous (−FLP) mutation rates in wild-type cells (C) without or (D) with ura3-1 on ChrV. Error bars show 1 SD, and significant increases over spontaneous are indicated. *P < 0.05, **P < 0.01, ***P < 0.001. (E) Estimated rates of point mutations, GCRs, and ura3-1 conversions. Fold changes above spontaneous are indicated.
