The relative lack of biochemical data on many large subunit proteins certainly hinders the fitting at this resolution. Notably, while the RNAs of the archael and eubacterial ribosomes are quite ...

Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...
