In a giant feat of genetic engineering, scientists have created bacteria that make proteins in a radically different way than all natural species do. By Carl Zimmer At the heart of all life is a code.

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 ...

Nearly all living organisms use the same genetic code, a complicated mechanism by which genetic information is translated into proteins, the building blocks of life. A new study suggests conventional ...

The human genetic code is fully mapped out, providing scientists with a blueprint of the DNA to identify genomic regions and their variations responsible for diseases. Traditional statistical tools ...
