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

Superimposed on the genetic sequences coding for amino acids is a second genetic code. This second genetic code, which makes use of dual-use codons, or duons, specifies how genes are controlled. The ...

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 ...

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 ...

The genetic code is a set of instructions that direct the translation of DNA into 20 amino acids, the basic units of proteins in living cells. The genetic code is made up of codons, which are ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids ...

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 ...

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 ...
