Despite awe-inspiring diversity, nearly every lifeform—from bacteria to blue whales—shares the same genetic code. How and when this code came about has been the subject of much scientific controversy.

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 ...

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.

Forbes contributors publish independent expert analyses and insights. Recent breakthroughs in genetics research may have uncovered new genes underlying common psychiatric disorders. Schizophrenia and ...

Linguists have developed the comparison of the genetic code with language where nucleotides act as letters, and introduced the concept of "a semiotic nucleotide"—the minimal element that makes it ...
