Life runs on instructions you never see. Every cell reads DNA, turns that message into RNA, and then builds proteins that ...
Scientists have long believed that a universal genetic code serves as a blueprint for all life on Earth, dictating the structure and function of organisms from the simplest bacteria to complex humans.
The traditional explanation of the initial genetic code in life seems less established when ancient proteins seem to be ...
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.
