Biologists have shown that the surfaces of plant leaves are coated with a diverse array of RNA molecules. The finding suggests that the RNA present on the leaf surface may play a role in shaping the ...

That’s a big problem, because the precise shape that an RNA molecule folds into determines its function. One day, scientists hope to create RNA machines that could become the basis of lifesaving ...

Transfer ribonucleic acid (tRNA) is a type of RNA molecule that helps decode a messenger ... structure with three hairpin loops that form the shape of a three-leafed clover. One of these hairpin ...
