"The genetic code is this amazing thing in which a string of DNA or RNA containing sequences of four nucleotides is translated into protein sequences using 20 different amino acids," said Joanna Masel ...

A team from the University of Illinois has uncovered surprising evolutionary links between the genetic code and tiny protein fragments called dipeptides. By analyzing billions of dipeptide sequences ...

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 ...

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 reasons why people attempt suicide include triggers like trauma and stress, as well as inherited genetic factors. A new study has identified 12 DNA variants, or variations in the human genetic ...
