Fig. 1From: Mollusc genomes reveal variability in patterns of LTR-retrotransposons dynamicsSchematic structure of LTR-retrotransposons elements. The long terminal direct repeats, flanking the elements, are represented by oriented red arrows and the two classical open reading frames by the two large rectangles. In the pol gene, the relative position of the domains that encode all the proteins required for transposition are detailed, in particular the integrase positionBack to article page
