Scientists have discovered a microbe that bends the rules of the genetic code. This organism, Methanosarcina acetivorans, ...

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 ...

The genetic code is not frozen. Genetic code variations found in microorganisms include codon bias, codon reassignment, ambiguous decoding and natural genetic code expansion. Codon bias, which is ...

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 ...
