Cells working with an expanded genetic code could make more diverse medicines. A new study shows scientists are within striking distance. One of modern biologists' most ambitious goals is to learn how ...

Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

This circular diagram represents the genetic code, showing how the four nucleotide bases of RNA (adenine [A], cytosine [C], guanine [G], and uracil [U]) form codons that specify amino acids. Each ...

Peking University, June 27, 2025: To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University ...

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

A surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...

Proteins that were present during the origin of life may have consisted of only seven primordial amino acids, a study suggests. The 20 amino acids commonly found in proteins are encoded by a total of ...

DNA is admired for its perfection as a programmable information molecule: it uses repeating polymerization chemistry to link four nucleotide building blocks (adenine, cytosine, guanine, and thymine) ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This chart was used in the National ...
