We have isolated cytoplasmic ribosomes from Euglena gracilis and characterized the RNA components of these particles. We show here that instead of the four rRNAs (17-19 S, 25-28 S, 5.8 S and 5 S) found in typical eukaryotic ribosomes, Euglena cytoplasmic ribosomes contain 16 RNA components. Three of these Euglena rRNAs are the structural equivalents of the 17-19 S, 5.8 S and 5 S rRNAs of other eukaryotes. However, the equivalent of 25-28 S rRNA is found in Euglena as 13 separate RNA species. We… CONTINUE READING
