Classification of Helitrons in D. pulex based on structural features and conserved coding region. Alignment of (a) Helitron termini showing conservation across species, including HelidaphNA1.1 and HelidaphNA2.1, (b) the rolling-circle Rep domain showing conservation across species, including D. pulex, and (c) 5' and 3' ends of HelidaphNA1.1 copies found in tandem arrays in the genome.
