Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the budding ...

The dictionary of life has a new update. A DNA sequence that signals cells in almost all other organisms to stop synthesising proteins instead encodes a rare amino acid in some archaea, according to a ...

Two years ago, Ohio State University researchers surprised the scientific community by announcing their discovery of a 22nd genetically encoded amino acid. Now they have capped that discovery with ...

Scientists at The Scripps Research Institute (TSRI) report in an upcoming article in the Journal of the American Chemical Society their synthesis of a form of the bacterium Escherichia coli with a ...

Researchers have engineered bacteria to synthesize an amino acid that contains a rare functional group that others have shown to have implications in the regulation of our immune system. The ...

Mutations can occur on several levels, including genetic, but can also take the form of amino acid replacements during protein synthesis. Amino acid replacements can be deleterious, neutral, or ...
