Scientists Rewrite the Genetic Code of E. Coli, and It’s Drastically Different From Anything Found in Nature The synthetic bacteria contain a shorter genetic code with 57 codons rather than 64 ...

Now, another group of scientists, some of whom worked on Syn61, have managed to further reduce the genetic code of E. coli down to 57 codons, making Syn57.

Bacteria built with smallest genetic code ever The engineered Escherichia coli have only 57 codons compared with the usual 64 ...

Now, scientists have redesigned the genetic code of the bacterium Escherichia coli to contain just 57 of the 64 codons. The findings were published in late July in Science.
