An essential cellular enzyme successfully transcribed synthetic DNA letters, bringing expanded genetic codes closer to biological use.

Nevertheless, some preliminary steps have been taken. Researchers have managed to add some new amino acids to a bacterial ...

Researchers at UC San Diego have demonstrated that a key cellular enzyme can accurately read an eight-letter genetic alphabet ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...
