title: Genes coding for 5S ribosomal RNA of the nematode Caenorhabditis elegans.
abstract: We have identified a 1-kb genomic sequence that represents the major class of 5S rRNA genes in the nematode Caenorhabditis elegans. This 1-kb sequence is tandemly repeated 110 times in the haploid genome forming a single homogeneous gene family. Other nematode genomic sequences, distinct from the major 1-kb repeat class but homologous to it, may represent dispersed 5S rRNA genes or the ends of a gene cluster. One such fragment shows a restriction fragment length difference between two C. elegans strains. This should allow the genetic analysis of 5S rRNA-coding DNA (5S X rDNA) and its flanking regions in C. elegans.
