Intron gain via transposon insertion. The solid black bar indicates intron-exon junctions. Red nucleotides indicate matched nucleotides between Doc1053 and intron 3 in Dsec\GM26034. Bolded and underlined nucleotides represent TSDs caused by insertion of the transposon. The first nucleotide in the downstream TSD likely underwent a G→C transversion. The insertion of Doc1053 did not change the reading frame of Dsec\GM26034 but did insert five amino acids (Thr, Met, Ser, Thr, and Glu).
