Ribonucleic acid (RNA) is, along with DNA and protein, one of the three primary biological macromolecules and was probably the first to arise in early life forms. In the "RNA world" hypothesis, RNA is able to support life ...

Scientists have long known that RNA encodes instructions to make proteins. The building blocks that comprise RNA—A, U, C, and Gs—form a blueprint for the protein-making machinery in cells. To make proteins, the machinery ...

Think of life as a house: if DNA molecules are blueprints, then messenger RNAs (mRNAs) are orders, describing the required parts (proteins) and when they should arrive. But putting in many orders doesn't always mean you'll ...

Protein synthesis is programmed by messenger RNAs, and when enough of a given protein has been made, the mRNAs that encode it are destroyed. LMU researchers have now shown that protein synthesis and mRNA degradation are structurally ...
