Quizplus · Accepted Answer

The start codon is AUG which codes for methionine. Therefore, the first amino acid added would be methionine. The codon UCUG codes for leucine, but it is in the wrong reading frame since it is not a multiple of three bases away from the start codon. Thus, it can be ignored. The next codon, GGC, codes for glycine. The final codon, UUU, codes for phenylalanine. Therefore, the correct order is methionine-glycine-phenylalanine, and the best choice is D.
