Genome-wide distribution of representative prl loci and their proximity to DSB peaks.

1Indicate the chromosome (Chr.), position, and direction (Dir.) of transcription (F, forward; R, reverse) for loci from which each prl ncRNA is transcribed. Direction of transcription is relative to the genome sequence.2Distances between prl loci and the nearest DSB peaks (left and right) were determined as described in the methods section. Because 88% of the observed DSBs (from peak area integrals) were classified previously as falling within prominent DSB peaks [23], we analyzed the data both for prominent DSB peaks and for all DSB peaks (prominent plus weak). Ends of prl molecules (loci) that map within DSB peaks were assigned distance values of zero.3N.a., not applicable. There is no known DSB peak between the prl locus and the end of the chromosome, so no distance could be determined.
