Stop Codons
In
classical genetics, the
stop codons were given names: UAG was amber, UGA was opal, and UAA was ochre. These names were
originally the names of the specific genes in which
mutation of each of these
stop codons was first detected.

Oh, I wish it were as easy as just finding a start and finding a stop. A
start codon for a
protein is "ATG." You're going to bump into a
start codon ATG pretty often.
