  1. The coverage is shown for major-form distal (DΔ4) and proximal (PΔ4) tandem donors. Genes with inferred DΔ4 splicing exons outnumber genes with PΔ4 splicing exons about 2.5-fold, which is reflected in their overall cDNA (about three-fold) and EST (about ten-fold) coverage. In addition to/GT, the/GY motif is shown, if the presence/GC was statistically significant.
