a, Nascent and mature transcripts initiating from URA1 and RPL5 promoters in the sense and antisense directions. Note that there are cryptic unstable transcripts (CUTs) in the antisense direction for URA1 but not RPL5. b, A histogram of the transcription ratio (antisense/sense transcription levels) for 1,875 genes. The green and grey boxes indicate the subset of genes with a ratio of less than 1:8 and less than 1:3, respectively. c, Antisense transcription levels are plotted versus sense transcription for each tandem gene (Spearman correlation coefficient, rs = 0.34). d, The level of antisense transcription for each promoter is plotted versus the local enrichment for H4 hyperacetylation using available data24 (rs = 0.65).
