Sequence alignments of the nine 8-bp direct repeats (DR I) (A), the six 17-bp imperfect direct repeats (DR II) and a partial homologous sequence (B), and the five 7-bp imperfect direct repeats (DR III) and a partial homologous sequence (C). The consensus sequences are shown below the sequence alignments. Two pairs of IRs, which are overlapped with DRs, are noted by rightward and leftward arrows above DR sequences in panel A.
