RNA (rRNA) from all organisms contains modifications, and there is a correlation between the overall complexity of an organism and the number of modified nucleosides in its rRNA. The rRNA of the most primitive bacteria, such as some . species, may possess only 14 modified nucleosides (de Crécy-Lagar

ytic cycle of EF-Tu (Figure 1) can be subdivided into five phases: (1) the binding of EF-Tu•GTP to elongator aa-tRNAs; (2) the binding of the resulting ternary complex to the ribosomal A/T site where codon sampling occurs; (3) a conformational change of both the ribosome and the ternary complex with

While much of the riboswitch-related research has focused on the remarkable ability of different aptamer domains to adopt the intricate structures required to bind a spectrum of biological
