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

Two studies provide insights into the distinct strategies used by prokaryotes and eukaryotes to pause translation in order to facilitate cotranslational targeting of membrane proteins to the ...

During decoding, a codon of messenger RNA is matched with its cognate aminoacyl-transfer RNA and the amino acid carried by the tRNA is added to the growing protein chain. Here we propose a molecular ...

Scientists have discovered a microbe that bends the rules of the genetic code. This organism, Methanosarcina acetivorans, uses a flexible translation process. One codon, UAG, traditionally a stop ...

This is a preview. Log in through your library . PNAS is the world's most-cited multidisciplinary scientific serial. It publishes high-impact research reports, commentaries, perspectives, reviews, ...

DNA has often been called “the book of life,” but this popular phrase makes some biologists squirm a bit. True, DNA bears our genes, which spell out the instructions our cells use to make ...

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 ...

Biologists have revealed a hidden code that determines the expression level of a gene, providing a way to distinguish efficient genes from inefficient ones. The research involved creating hundreds of ...

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 ...
