  1. The first column indicates the different transposed elements (TEs) that were examined. In columns 2 and 3, the numbers of exonizations in the sense and antisense orientations are shown. The percentages of the total number of exonizations are given in parentheses. In columns 4, 5, and 6, the numbers of exons are given in which the TE contributes the whole exon, the 5', and the 3' part of an exon, respectively. In parentheses are given the percentage of the total number of exonizations. LTR, long terminal repeat; MIR, mammalian interspersed repeat; RE, retroelement.
