A single swap in the letters of a gene’s sequence could modify the protein it encodes, even if the switch doesn’t change which amino acids make up the molecule, researchers report. The finding could ...

Discover the unique genetic code of Euplotes crassus, where a single codon can represent two amino acids, challenging universal genetics. Living things, from bacteria to humans, depend on a workforce ...

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 ...

Living things, from bacteria to humans, depend on a workforce of proteins to carry out essential tasks within their cells. Proteins are chains of amino acids that are strung together according to ...
