Codons
From :


 * A The codon AUG both codes for methionine and serves as an initiation site: the first AUG in an mRNA's coding region is where translation into protein begins. The other start codons listed by GenBank are rare in eukaryotes and generally codes for Met/fMet.
 * B The historical basis for designating the stop codons as amber, ochre and opal is described in an autobiography by Sydney Brenner and in a historical article by Bob Edgar.
