D
Tryptophan
Verified step by step guidance1
Understand the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein, where mRNA codons specify amino acids during translation.
Recall that the genetic code is degenerate, meaning that most amino acids are encoded by more than one codon, except for a few that have a single codon.
Identify the amino acids listed: Asparagine, Leucine, Methionine, and Tryptophan, and recall their codon usage.
Note that Methionine and Tryptophan are each encoded by a single codon (AUG for Methionine and UGG for Tryptophan), so they do not have multiple codons.
Recognize that Leucine is encoded by six different codons, making it the amino acid among the options that is encoded by more than one mRNA codon.
