Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the ...

This diagram depicts the chemical structure of pyrimidine, a six-membered aromatic ring with two nitrogen atoms at positions 1 and 3 (highlighted in blue). The remaining positions are occupied by ...

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 ...

Researchers from ETH Zurich have modified a bacterial transport system so that it can efficiently introduce large quantities of unnatural amino acids into cells, disguised as a kind of Trojan horse.
