Life runs on instructions you never see. Every cell reads DNA, turns that message into RNA, and then builds proteins that keep you alive. That translation system feels so basic that it is easy to ...

For the first time ever, all five letters of the genetic code were found together on a rock from space
The question of how life began on Earth has never been fully answered. Scientists have long debated whether the organic molecules required for biology were cooked up in the conditions of early Earth ...
The genetic code acts as life's instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...
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 ...
