For decades, biology students have learned one rule about the genetic code that supposedly has no exceptions: three specific DNA sequences act as stop signs, telling the cell’s protein-building ...

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.

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 ...
