Question

multiple-choice question
the three letters aug is an example of a(n) ____________.
amino acid
codon
trna
anticodon

Explanation:

A codon is a sequence of three nucleotides (like AUG) that codes for an amino acid or a start/stop signal in protein synthesis. Amino acids are the building blocks of proteins, tRNA (transfer RNA) carries amino acids, and an anticodon is a sequence on tRNA complementary to a codon. AUG is a codon (it can be a start codon or code for methionine).

Answer:

B. codon (assuming the second option is labeled B; if the options are in order as shown, the correct one is the second option with "codon")
