Fig. 3From: Full-length mRNA sequencing uncovers a widespread coupling between transcription initiation and mRNA processingAlternative TSSs and exons are significantly associated with known and novel poly(A) signals. a Bar charts show the number and relative proportion of PASs that are associated with canonical or non-canonical poly(A) signals for all PASs, PASs with significant coupling, and alternative exon- and/or TSS-linked PASs. b Bar charts represent the number and relative proportion of known and unknown poly(A) signals for TSS-linked, exon-linked, or TSS- and exon-linked PASsBack to article page
