The genetic code is a set of rules defining how the four-letter code of DNA is translated into the 20-letter code of amino acids, which are the building blocks of proteins. The genetic code is a set ...

Starting from the four innermost letters and working to the outermost ring, this table shows shows which three-letter base sequence or codon encodes which amino acid. In the journal Angewandte Chemie ...

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 ...

Living organisms synthesize a staggering variety of proteins by combining 20 amino acids into chains of any length and order. In the past, to expand protein diversity beyond the scope of these 20 ...

Transcription and translation are processes a cell uses to make all proteins the body needs to function from information stored in the sequence of bases in DNA. The four bases (C, A, T/U, and G in the ...

Two teams of researchers from Ohio State University reported today that they had identified the 22nd genetically encoded amino acid, a discovery that is the biological equivalent of physicists finding ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...
