Annotation status and cumulative arrival of exon-exon splice junctions. a The number of exon-exon junctions present in at least x human runs accessions. Colors represent different degrees to which the junctions are annotated: completely annotated (purple) both donor and acceptor annotated but not in combination with each other (exon skip, blue), only donor or only acceptor annotated (one annotated, green), and neither annotated (red). Curves are cumulative across categories; thus, the number of unannotated junctions is given by the difference between the purple and red lines. b The same as (a) but for mouse run accessions. c The cumulative number of exon-exon junctions (in millions) across time for four different thresholds for the number of human run accessions where a junction is observed. d The same as (c) but for mouse run accessions
