DNA strand-exchange patterns associated with double-strand break-induced and spontaneous mitotic crossovers in Saccharomyces cerevisiae
Fig 7
Spontaneous COs in which each product contains hetDNA.
White, black, and gray boxes represent lys2Δ5′, lys2Δ3′ and hetDNA, respectively. Potential initiation sites are marked with vertical red lines. (A) COs with a hetDNA pattern consistent with an initiating DSB in the lys2Δ5′ allele. (B) COs with a hetDNA pattern consistent with an initiating DSB in the lys2Δ3′ allele. (C) COs exhibiting a hetDNA pattern consistent with initiation by a single-strand nick. (D) COs containing a hetDNA pattern consistent with initiation by a single-strand gap. “n” is the number of events with the relevant hetDNA pattern.
