The following features occur during protein synthesis: (i) Movement of m-RNA from the nucleus into the Cytoplasm, where it binds to the ribosomes (ii) Formation of amino acyl t-RNA complex (iii) Transcription of specific segments of DNA into m-RNA molecules in the nucleus (iv) Binding of N-terminal amino acid, methionine t-RNA to the 'P' site of the ribosome. The t-RNA anticodon "pairs with AUG on m-RNA" (v) Formation of peptide bond between first and second amino acids at the 'A' site (vi) Release of the completed polypeptide chain from ribosomes (vii) Migration of dipeptide to form a tripeptide and then a polypeptide The correct order of events is
