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 ...
Unveiling a new chapter in the understanding of human genetics, scientists have discovered a hidden geometric code within our DNA. This code, embedded in the three-dimensional structure of DNA, goes ...
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.
