For comparison, the D. melanogaster P-element terminal sequences are included but not aligned. The red box indicates BuT5 and P-element TIRs, the orange box BuT5 and P-element sub-TIRs, and the pink box the D. melanogaster P-element TIRs. Green arrows indicate the primers BL (dark green) and BR (light green).
