RESUMO
The genes which code for the 5S ribosomal RNA in the newt, Notophthalmus viridescens have been cloned and analyzed. Two types of repeating unit were detected: a major type consisting of a 120 bp coding region with a 111 bp spacer, and a minor type composed of a coding region, a pseudogene, and a 113 bp spacer. The pseudogene is a 36 bp segment which corresponds to the 3' terminal third of the 5S RNA gene, and is situated immediately 3' to the gene, being separated from it by 2 bp. Two recombinant plasmids were obtained in which the major and minor units were arranged in an interspersed pattern.
