Alignment of the nucleotide sequences of RoDIRS1 element termini and ICRs. In this alignment the left terminus (lTer) and the right ICR (rICR) sequences are represented with the inverse complementary sequences of the right terminus (rTer) and the left ICR (lICR) sequences. The left and right extensions (lE and rE) of the terminal regions are indicated by orange and brown boxes. The portion called "divergent ITRs" represents the part of the ITRs that is mostly complementary to the corresponding ICRs. The region that is conserved among the four different sequences is underlined in purple.
