Genus Merluccius is considered one of the most important groups within the Teleostei, and comprises 12 extant species distributed along the coasts of America, Europe and Africa, being its fisheries very important in these continents. Despite their noticeable economical importance for humans, to date the phylogeny of hakes has not been clearly established.(More)
The molecular organization of the 5S rRNA gene family has been studied in a wide variety of animal taxa, including many bony fish species. It is arranged in tandemly repeated units consisting of a highly conserved 120 base pair-long region, which encodes for the 5S rRNA, and a nontranscribed spacer (NTS) of variable length, which contains regulatory(More)
BACKGROUND International fish trade reached an import value of 62.8 billion Euro in 2006, of which 44.6% are covered by the European Union. Species identification is a key problem throughout the life cycle of fishes: from eggs and larvae to adults in fisheries research and control, as well as processed fish products in consumer protection.

The 5S rDNA is organized in the genome as tandemly repeated copies of a structural unit composed of a coding sequence plus a nontranscribed spacer (NTS). The coding region is highly conserved in the evolution, whereas the NTS vary in both length and sequence. It has been proposed that 5S rRNA genes are members of a gene family that have arisen through(More)
