"WebmRNAs and tRNAs are transcribed separately from different genes (and in eukaryotes this is even done by different RNA polymerases). These two molecules do interact during during translation — aminoacyl-tRNAs (that is tRNA bound to the appropriate amino acid) bind to codons on an mRNA that is loaded onto a ribosome.

WebOct 3, 2011 · Three tRNA binding sites, designated aminoacyl (A), peptidyl (P), and exit (E) sites, are present in all prokaryotic and eukaryotic ribosomes. In the elongation cycle of a bacterial ribosome, the A site binds an aminoacyl-tRNA (aa-tRNA) as a ternary complex (TC), elongation factor Tu (EF-Tu)·GTP·aa-tRNA. WebDec 5, 2024 · Recent structural studies of the functional 70S ribosome in complex with mRNA and tRNAs in the P- and E-sites (peptidyl- and exit-tRNA–binding sites, respectively) show that the A1493 nucleotide adopts an extrahelical positon in the absence of tRNA within the decoding site ( 15 ).
