The genetic code is central to life. With minor variations, everything uses the same sets of three DNA bases to encode the same 20 amino acids. We have discovered no major exceptions to this, leading ...

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 ...

Decades of research has viewed DNA as a sequence-based instruction manual; yet every cell in the body shares the same genes – so where is the language that writes the memory of cell identities?

Most organisms on Earth have the same basic genetic code, but it comes with some flaws. Scientists sought to work out those errors by creating their own artificial genome, which replaced E. coli’s ...

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.

We have gone further than ever before in creating life that is unlike anything that has evolved naturally. The genome of an Escherichia coli bacterium has been redesigned on a computer to use just 57 ...
