Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → AUG
Option (1) AUG — Correct. AUG is the start (initiator) codon where translation begins. It also codes for methionine, so it has a dual function.
NCERT Extract:
Genetic Code – “… UUU would code for Phenylalanine (phe). Some exceptions to this rule have been found in mitochondrial codons, and in some protozoans. (v) AUG has dual functions. It codes for Methionine (met) , and it also act as initiator codon.”
