The DNA inside of living organisms is packed with information, so much so that it's hard to search genetic databases, but ...

An archaeon reads the same codon in two different ways, overturning a doctrine that has stood for 60 years. Living organisms ...

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 ...

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 ...

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 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 ...

After two decades in the making, scientists have cracked the code on a drug that can repair DNA, setting the scene for a new ...

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 ...

Darwin's theory of evolution should be expanded to include consideration of a DNA stability 'energy code' -- so-called 'molecular Darwinism' -- to further account for the long-term survival of species ...
