From: Horizontal transfer of a non-autonomous Helitron among insect and viral genomes
Nucleotide conservation at 5′- and 3-′ termini among non-autonomous Hel-2 Helitrons from insect and insect virus genomes. Alignment shows highly conserved nucleotides (highlighted black), and most prevalent alternate nucleotide (highlighted grey), and gaps are represented as a dash (−). Length and unit of internal tandem repeat arrays are shown. GenBank accession numbers and common names are respectively provided on the left and right of each sequence. Full-length annotated Hel-2 Helitrons used in this partial sequence alignment are provided in Additional file 4.
