A proposed nucleotide sequence for the 5S ribosomal ribonucleic acid of rainbow trout (Salmo gairdneri).

Rainbow trout cell cultures have been exposed to 32P-labelled inorganic phosphate and the labelled RNA has been isolated. The 5S ribosomal ribonucleic acid (5S rRNA) was purified by polyacrylamide gel electrophoresis, then digested with RNase T1 or pancreatic RNase. The products of complete digestion were separated and their sequences determined. These analyses have allowed a sequence to be proposed which differs in eight positions from that of mammalian 5S rRNAs.
