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 ...

Scientists have created Syn57, a completely synthetic bacterium with a genetic code unlike anything in nature. Unlike all known life, which uses 64 codons to build proteins, Syn57 only uses 57 — ...

Scientists in the UK have rewritten one of life’s oldest operating systems. They have built a bacterium that functions with a stripped-down genetic code, eliminating seven of the 64 instructions used ...

"The genetic code is this amazing thing in which a string of DNA or RNA containing sequences of four nucleotides is translated into protein sequences using 20 different amino acids," said Joanna Masel ...

Alex Marson of Gladstone and his collaborators at Stanford University developed a genomic mapping technique that helps close ...
