The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in ...

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 ...

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 ...

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) ...

A four-letter alphabet might seem limited, but it’s all nature needed to write the instructions for all life on the planet. News that researchers have added four letters to the genetic alphabet opens ...
