Quizplus · Accepted Answer

Reading the codons from the start codon AUG, the amino acids added in order would be methionine (AUG is the start codon), glycine (GGC), and phenylalanine (UUU). The codon following UUU is a stop codon (UGA), therefore the sequence ends. Choice A is incorrect because it includes an aspartic acid (GAU) codon, which is not present in the given sequence. Choice C is incorrect because it includes a valine (GUU) codon, which is not present in the given sequence. Choice D is incorrect because it includes a threonine (ACU) codon, which is not present in the given sequence.
