Chromosomal mapping of transposable elements of the rex family in the bristlenose catfish, ancistrus (siluriformes, loricariidae), from the amazonian region
Repetitive DNA sequences are present in the genome of basically every known organism, and transposable elements (TE) are one of the most representative sequences involved in chromosomal rearrangements and the genomic evolution of eukaryotes. In fish, the non-LTR retrotransposon TEs, Rex1, Rex3, and...
