A codon is a set of three nucleotides in a sequence of DNA or RNA that corresponds to a specific amino acid. There are codon usage is degenerate as 64 different codons code for 20 amino acids. Thus ...

A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

Cells use a genetic code to translate the information contained in DNA and RNA sequences into the amino-acid building blocks that make up a protein (Nirenberg et al., 1965; Söll et al., 1965). DNA ...

The genetic code has been proposed to be a ‘frozen accident,’ but the discovery of alternative genetic codes over the past four decades has shown that it can evolve to some degree. Since most examples ...

The extent to which alteration of endogenous tRNA modifications may be exploited to improve genetic code expansion efforts has not been broadly investigated. Modifications of tRNAs are strongly ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids ...
