The ribosome binds to the mRNA and reads the codon codeThe ribosome brings the correct tRNA molecules to each mRNA codon, using complementary base pairing between the mRNA codons and the tRNA anticodonsEach tRNA has an amino acid attachedThe ribosome catalyses the formation of peptide bonds between adjacent amino acidsThe ribosome then moves (translocates) to the next codon along the mRNAMultiple amino acids are joined to form a polypeptide
