Evolution in the block: common elements of 5S rDNA organization and evolutionary patterns in distant fish genera.

Genome - 1 Jan 2012

Campo Daniel, García-Vázquez Eva

Abstract excerpt

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 concerted evolution. In this study, we describe the molecular...
