Figure 6

Detection of polyadenylation. The proportion of the polyadenylation sites perfectly matching the annotated 3′ ends of known genes is shown in the center of the diagram. Subsequent rings going outwards show the percentage of tentative polyadenylation sites successively further away from the known 3′ ends. The percentages without brackets are based on the total of 5,229 sites found with zero mismatches, while bracketed percentage values correspond to the total of 6,801 sites allowing up to one mismatch – see text for details.
