61 codons specify one of the 20 amino acids that make up proteins 3 codons are stop codons, which signal the termination of protein synthesis Importantly, the genetic code is nearly universal, shared ...

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 same amino acid can be encoded by anywhere from one to six different strings of letters in the genetic code. Andrzej Wojcicki/Science Photo Library via Getty Images Nearly all life, from bacteria ...

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 ...

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 ...

A surprising number of microbes use alternate genetic codes, different from the standard genetic code that governs the large majority of life. A census of these "recoded" genomes was recently reported ...

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence in ...

In the largest screen to date for alternative genetic codes, a computer program named Codetta scanned more than 250,000 genome sequences from bacteria and archaea to identify five never-before-seen ...

Synthetic biologists from Yale were able to re-write the genetic code of an organism - a novel genomically recoded organism (GRO) with one stop codon - using a cellular platform that they developed ...
