A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers ...

Genetic code surprise: An Oxford pond microbe uses two universal stop codons to code for amino acids, breaking a key rule of molecular biology. Why it matters: The discovery could alter evolutionary ...

Genetic rule broken: Researchers found ciliates that treat stop codons as amino acid instructions, defying the universal genetic code. Two remarkable cases: Condylostoma magnum reassigns all three ...

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 ...
