title: Clusters of 5S rRNAs in the intergenic region of ubiquitin genes in Tetrahymena pyriformis.
abstract: Here, we report the molecular analysis of two independent 5S rRNA clusters found in the intergenic region of two ubiquitin genomic clones isolated from Tetrahymena pyriformis. Each cluster contains two 120-bp-long coding regions organized in tandem with 142/145-bp-long spacers.
