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

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 ...

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 ...

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

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, ...

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 ...

As wildly diverse as life on Earth is—whether it’s a jaguar hunting down a deer in the Amazon, an orchid vine spiraling around a tree in the Congo, primitive cells growing in boiling hot springs in ...

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 ...
