<P> Prokaryotic translation is the process by which messenger RNA is translated into proteins in prokaryotes . </P> <P> Initiation of translation in prokaryotes involves the assembly of the components of the translation system, which are: the two ribosomal subunits (50S and 30S subunits); the mature mRNA to be translated; the tRNA charged with N - formylmethionine (the first amino acid in the nascent peptide); guanosine triphosphate (GTP) as a source of energy, and the three prokaryotic initiation factors IF1, IF2, and IF3, which help the assembly of the initiation complex . Variations in the mechanism can be anticipated . </P> <P> The ribosome has three active sites: the A site, the P site, and the E site . The A site is the point of entry for the aminoacyl tRNA (except for the first aminoacyl tRNA, which enters at the P site). The P site is where the peptidyl tRNA is formed in the ribosome . And the E site which is the exit site of the now uncharged tRNA after it gives its amino acid to the growing peptide chain . </P>

In which ribosome site(s) is an amino acid bound to its corresponding trna
