''Osser'' constitutes a one-single-sequence clade within Branch 2 of the ''Ty1/Copia'' LTR retrotransposons family ([[Literature:100596|Llorens ''et al''. 2009]]) as it has no phylogenetic relatives to date reported. The full-length ''Osser'' genome is 4885 bp in size, including two identical 197-bp LTRs. The internal region of this element presents a Primer Binding Site (PBS) for a tRNA&lt;sup&gt;Met&lt;/sup&gt;, two overlapping Open Reading Frames (ORFs) containing the typical ''gag'' and ''pol'' domains of ''Ty1/Copia'' LTR retrotransposons: gag (in which is present the zinc finger motif of Cys-His type characteristic of the nucleocapside domain), protease, integrase, reverse transcriptase and ribonuclease H; and a Polypurine Tract (PPT) upstream its 3’ LTR ([[Literature:44101|Lindauer ''et al.'' 1993]]).<br /> |structure=osser.png<br /> |host=Volvox carteri<br /> |hostpic=volvox_carteri.jpg<br /> |literature=*[[Literature:15303|Mobile DNA II.
