Figure 2.
APA classes and illustrations of the locations of MPSS-DGE and SBS-DGE tags. The symbols are annotated on the bottom. Tag locations mark where the tag is mapped on the gene. The nearest DpnII site (open triangle) indicates a potential tag location that is not found in the pool of experimentally sequenced tags, meaning that a poly(A) site should be located between the tag and the next DpnII site (Meyers et al. 2004b). The numbers of the three columns on the right side are the distributions of the MPSS-DGE or SBS-DGE tags in each APA-class.
