Chromoviruses
Chromoviruses have long terminal repeats in direct orientation at each end. The genes within the chromovirus encode Gag and Pol proteins. The following enzymatic domains in pol gene are indicated: PR, protease; RT, reverse transcriptase; RH, RNaseH; IN, integrase; and CHR, chromodomain. WebRetroviruses are present in genomes of early eukaryotes but significantly expanded in vertebrates. Gypsy-like retroviruses (aka chromoviruses, defined via RT and gag similarity) are often found conserved as full-length elements including env genes in most lower eukaryote genomes (e.g., Caenorhabditis elegans), but
