Additional file 1 of Genes divided according to the relative position of the longest intron show increased representation in different KEGG pathways

Supplementary Material 1. Figure S1: Comparison of the absolute and relative positions of the longest introns among orthologous genes of 6 vertebrates. Twenty randomly selected human genes and their corresponding orthologs were monitored in each of the groups with the longest human intron in the 1st tertile (A), 2nd tertile (B) and 3rd tertile (C).
