Class I elements — also called retrotransposons, which Rio de Janeiro, Brazil Full list of author information is available at the end of the articleBackground Transposable elements (TEs) are genetic elements that share the main characteristic of amplifying their own representation within genomes. Due to their ability to spread in the absence of selection at the host level, they persist in genomes even at the expense of a net negative fitness to the hosts [1]. Under this view, these elements are conceived as genomic parasites. Today, the view of TEs within genomes has changed considerably, and these elements have been shown to be major contribu-tors to both genome evolution and function [2-5]. The relationships between TEs and host genomes where they reside are now considered a continuum from parasitic t
