A large ribosomal subunit bonds to the initiation complex. The codon adjacent to the initiation codon bonds to its complementary anticodon, which is part of a free tRNA. The two amino acids still attached to their tRNAs align. With the help of rRNA, amino acids form peptide bonds. Then, the first tRNA is released.
Peptide bonds always bind the acid end of one amino acid with the amino end of the next (Fig. 6). Peptide bonds are strong covalent bonds which keep the amino acids connected during and after translation. tRNA can now come into this site if it has the anticodon that is complementary to the next codon on the mRNA (Figs. 20,21). The ribosome will then form the peptide bond between the third and second amino acids and kick off tRNA number two (Fig. 21). The third tRNA now binds a chain of three amino acids.
