उत्तर
| Feature | Code | Codon | Anticodon |
| Definition | The universal set of rules relating nucleotide triplets to amino acids. | A specific sequence of three nucleotides that codes for an amino acid. | A three-nucleotide sequence that is complementary to an mRNA codon. |
| Location | Present across the entire genome (DNA/mRNA). | Found on the mRNA strand. | Found on the tRNA molecule. |
| Function | Acts as the “biological dictionary” for protein synthesis. | Provides the actual instructions for which amino acid comes next. | Acts as the “key” to ensure the correct amino acid is delivered. |
| Base Pairing | N/A | Pairs with the tRNA anticodon. | Pairs with the mRNA codon. |
| Direction | 5’ → 3’ (Standard) | Read in the 5’ → 3’ direction. | Oriented in the 3’ → 5’ direction to bind properly. |
| Total Number | 64 different codons. | 64 possible triplets (including 3 stop codons). | Fewer than 64 (due to the Wobble effect). |
| Example | AUG = Methionine | AUG | UAC |
