Abstract
In higher eukaryotes, the 5S ribosomal multigene family (5S rDNA) consists of tandemly arrayed repeated units each one composed by a coding region (5S rRNA gene) and a non-transcribed spacer (NTS). It is already known that the distribution of 5S rDNA is highly conserved among related species, although several intra-and inter genomic variants of 5S rDNA units have been detected. These vari…
