Genetic code of an organism is not cast in stone. There are many exceptions to the standard codon table. Pawan Kumar Dhar reviews recent work to find that it is possible to plug in synthetic amino ...

A surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...

It has long been assumed that there is only one 'canonical' genetic code, so each word means the same thing to every organism. Now, this paradigm has been challenged by the discovery of large numbers ...
