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 ...

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

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 ...

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) ...

Scientists have discovered a microbe that bends the rules of the genetic code. This organism, Methanosarcina acetivorans, ...

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 ...

Gene editing can repair mutations that prematurely halt protein synthesis, resulting in incomplete peptides that cause various diseases. However, other approaches achieve the same effect without ...

Moving far beyond the capabilities of traditional oligonucleotide synthesis, the advent of advanced synthesis technologies is enabling genetic constructs to be made more rapidly, accurately, ...

LA JOLLA, CA—One of modern biologists’ most ambitious goals is to learn how to expand or otherwise modify the genetic code of life on Earth, in order to make new, artificial life forms. Part of the ...
