| S. No. | Salient features of genetic code | Reason |
| (i) | The codon is a triplet. | e.g., AUG, UUU, etc, are triplets |
| (ii) | One codon codes for only one amino acid,hence it is unambiguous and specific. | e.g., UUU codes for serine, AUG for methionine, etc. |
| (iii) | AUG has dual function as it codes for methionine and it also acts as initiator codon. | AUG is seen at the beginning of the polypeptide chain. |
| (iv) | UAG does not code for any amino acid hence iscalled stop codon and leads to end of translation. | No amino acid is coded by UAG in the polypeptide chain given. |
