Tandemly arranged variant 5S ribosomal RNA genes in the yeast Saccharomyces cerevisiae.

RESUMO
Most of the ribosomal RNA genes of the yeast Saccharomyces cerevisiae are about 9 kilobases (kb) in size and encode both the 35S rRNA (processed to produce the 25S, 18S, and 5.8S species) and 5S rRNA. These genes are arranged in a single tandem array of 100 repeats. Below, we present evidence that at the centromere-distal end of this array is a tandem arrangement of a different type of rRNA gene. Each of these repeats is 3.6 kb in length and encodes a single 5S rRNA. The coding sequence of this gene is different from that of the "normal" 5S gene in three positions located at the 3' end of the gene.
