Final answer:
The AUG triplet is correctly identified as a start codon in translation, marking the beginning of the protein synthesis process and setting the reading frame for subsequent codons.
Step-by-step explanation:
The statement that AUG is commonly used as a start codon during translation is indeed true. During the process of protein synthesis, the codon AUG has a pivotal role, as it not only codes for the amino acid methionine but also signals the initiation of translation by establishing the reading frame of the mRNA.
Consequently, every subsequent triplet group of nucleotides is read in this frame until a stop codon, which does not code for any amino acid, is encountered, and protein synthesis is terminated.
