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 ...

Starting from the four innermost letters and working to the outermost ring, this table shows shows which three-letter base sequence or codon encodes which amino acid. In the journal Angewandte Chemie ...

There are 20 canonical amino acids that are encoded by the genetic code of nearly all known organisms - there are only very few exceptions. In order to add novel building blocks to this existing ...

Scientists trying to engineer biologic molecules with new functions have long felt limited by the 20 amino-acid building blocks. Researchers are working to develop ways of putting new building ...

A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

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 ...

The code of life is simple. Four genetic letters arranged in triplets—called codons—encode amino acids. These are the building blocks of proteins, the machinery that powers life. But the genetic code ...

We have gone further than ever before in creating life that is unlike anything that has evolved naturally. The genome of an Escherichia coli bacterium has been redesigned on a computer to use just 57 ...
