Hidden within the genetic code lies the "triplet code," a series of three nucleotides that determine a single amino acid. How did scientists discover and unlock this amino acid code? Once the budding ...

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 ...

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 ...

Scientists trying to engineer biologic molecules with new functions have long felt limited by the 20 amino-acid building blocks. Researchers are working to develop ways of putting new building ...

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 ...

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 ...
