Figure 4From: Sequence determinants in human polyadenylation site selectionUracil frequencies in a 11 nt window, in the vicinity of "control" sites and two types of "unique" poly(A) sites: those located less than 300 nt from the Stop codon (CDS overlap: 1328 sequences), and those located more than 300 nt from the Stop codon (no CDS overlap: 2448 sequences).Back to article page
