Editing Stop codon (section)

=== Alternative stop codons ===
There are [[Genetic code#Variations|variations on the standard genetic code]], and alternative stop codons have been found in the [[Mitochondrial DNA|mitochondrial genome]]s of [[vertebrate]]s,<ref>{{Cite journal |last1=Barrell |first1=B.
