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 ...

UC Berkeley scientists discovered that a microbe can interpret the UAG stop codon in two ways, producing different proteins ...

Pyrrolysine is an important component of methyltransferase enzymes, which the archaea use to metabolize methylamine in the environment. “The need for that metabolism and availability of the machinery ...

While testing a new way to sequence genes, researchers stumbled upon a very rare divergence in the genetic code, which translates genetic sequences into proteins. The discovery was made in an organism ...

There are many possible three-letter genetic codes that could adequately encode protein sequences, but what about the need to encode higher-order information on binding and splicing sites? New ...

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 ...

All living things on Earth use a version of the same genetic code. Every cell makes proteins using the same 20 amino acids. Ribosomes, the protein-making machinery within cells, read the genetic code ...

Approximately one in five adults with spontaneous coronary artery dissection with high-risk features had an increased burden of rare genetic variants on whole-exome sequencing, suggesting testing may ...

DNA consists of a code language comprising four letters which make up what are known as codons, or words, each three letters long. Interpreting the language of the genetic code was the work of ...
