Unexpected genetic twist: An Oxford pond organism uses two universal stop codons to code for amino acids instead of ending ...

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

Rule-breaking discovery: A freshwater ciliate uses stop codons to build amino acids instead of ending proteins, defying the 'universal' genetic code. Genetic code flexibility: The organism reassigns ...

A team of biochemists has discovered in bacteria a protein capable of building DNA without following known genetic ...

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 ...

Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to be the way it is? "We find ...
