Characterization of 5.8S ribosomal ribonucleic acid in Neurospora crassa.
Neurospora crassa ribosomes contain a species of ribonucleic acid (RNA) of molecular weight 54,000, similar to 5.8S ribosomal RNA previously described for other eukaryotic organisms. The 5.8S RNA from N. crassa was found to be released by heat treatment at 60 C from 25S ribosomal RNA but not from 18S ribosomal RNA. The base composition of N. crassa 5.8S RNA was similar to that of 5.8S RNA from Saccharomyces cerevisiae, but differed from animal 5.8S RNA. During the course of this study, it was discovered that N. crassa 25S ribosomal RNA had a number of internal cleavages that may exist in vivo.
