1The codon ATG both codes for methionine and serves as an initiation site: the first ATG in an mRNA's coding region is where translation into protein begins.
2UGA can also code for selenomethionine: the twenty-first amino acid, discovered in 1986.
3UAG can also code for pyrrolysine: the twenty-second amino acid, discovered in 2002.
