Prokaryotic organisms contain one type of rRNA gene that encodes three distinct RNA species: the 23S, 5S, and 16S rRNAs. In comparison, eukaryotic cells contain two types of rRNA genes that give ...
Large Subunit rRNAs: The large subunit in prokaryotes contains the 23S and 5S rRNAs, while in eukaryotes ... This discovery led to the concept of the ribosome as a ribozyme, an RNA molecule with ...
as does the export of 5S ribosomal RNA. The function of these multiple mRNA export factors is not yet certain. Yra1, other mRNA-binding proteins, the cap-binding proteins Cbp20 and Cbp80 ...
