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.
