Question:
Dual functions of codon AUG
Dual functions of codon AUG
Show Hint
Remember, AUG is the start codon in translation and codes for methionine, which is important for the initiation of protein synthesis.
Updated On: Mar 6, 2026
- \( \text{Initiator codon and code for phenylalanine} \)
- \( \text{Universal codon and code for phenylalanine} \)
- \( \text{End codon and code for methionine} \)
- \( \text{Initiator codon and code for methionine} \)
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: The codon AUG serves dual functions in protein synthesis. It acts as the initiator codon, signaling the start of translation. Additionally, it codes for methionine, the first amino acid incorporated into the polypeptide chain during protein synthesis. Therefore, the correct option is that AUG serves as the initiator codon and codes for methionine.
