WebThis process of arrival of tRNA- amino acid complex, formation of the peptide bond, ribosomal translocation, and removal of the previous tRNA, are repeated. As ribosomes move over the mRNA, all the codons on mRNA are exposed one by one for translation. Termination and release of polypeptide: Towards the 3’ end of mRNA, there is a stop … WebOnly the right tRNA can enter the ribosome and pair with the code on mRNA. Once the tRNA and mRNA match, the previous tRNA (in the P site) will donate its growing protein chain onto this amino acid (still in A site). Then, both tRNAs move one site forward (A to P; P to E). “Uncharged” or empty tRNA will prepare to exit from the E site.
