They observed that the mRNA emerging from RNAP was bound to the small ribosomal subunit (30S) particularly efficiently when ribosomal protein bS1 was present, which helps the mRNA unfold in ...

The 30S subunit contains a 16S ribosomal RNA (rRNA) molecule, while the 50S subunit harbors 23S and 5S rRNA molecules. In contrast, eukaryotic cells have 80S ribosomes, which are larger and more ...
