The ribosome has three binding sites for tRNA molecules that span the space between the two ribosomal subunits: the A (aminoacyl), P (peptidyl), and E (exit) sites. In addition, the ribosome has two other sites for tRNA binding that are used during mRNA decoding or during the initiation of protein synthesis. These are the T site (named elongation factor Tu) and I site (initiation). By convention, the tRNA binding sites are denoted with the site on the small ribosomal subunit liste… 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.
