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 ...

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 ...

A study that analyzed the genetic code of a quarter of a million U.S. volunteers found more than 275 million entirely new variants that may help explain why some groups are more prone to disease than ...

Scientists testing a new method of sequencing single cells have unexpectedly changed our understanding of the rules of genetics. The genome of a protist has revealed a seemingly unique divergence 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?

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 ...

In this AI-generated illustration of Earth at the dawn of life, a distant volcano towers over shallow pools of water. It is possible the earliest life forms evolved in such environments. Credit: ...

An introner jumped between this species, a glass sponge, and an unrelated species of marine protist called a dinoflagellate. Image courtesy of the NOAA Office of Ocean Exploration and Research, ...
