Caltech researchers have identified a novel chemical reaction that could explain the formation of the building blocks of DNA ...

Life on Earth may have started with a molecule that still runs our cells today. As researchers probe ribonucleic acid in the lab and in ancient rocks and space dust, RNA is yielding clues that are far ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

A forested hill and clouds are in the background of an image of a shallow pool of steaming water, with the ground underneath colored in shades of beige, red, and brown. Life may have first emerged in ...

Recent research showed that an artificially constructed self-replicating RNA system modeling primitive life at the origin of ...

On the left are three forms of the same RNA molecule, which is stabilised into a single form (on the right) by mitoxantrone. Ribonucleic acids (RNAs) serve as messengers between DNA and protein ...

Although there are striking differences between the cells that make up your eyes, kidneys, brain and toes, the DNA blueprint for these cells is essentially the same. Where do those differences come ...
