C.
AUG
AUG codes for Methionine (Met) that is used as a start signal in protein syntheis. Hence, it is an initiation codon.
Also, in prokaryotes, codons GUG and UUG are the start codons.
UAA (ochre), UAG (amber) and UGA (opal) are the non- sense codons as they do not code for any amino acid. Their main function is to terminate the message for gene controlling protein synthesis. Therefore, termed as chain termination or stop codons.
UUU (uracil) codes for phenylalanine.
