RNA polymerase, the enzyme that synthesizes RNA from DNA during transcription, has been captured mid-reaction for the first ...

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 ...

A single enzyme that can generate all four nucleotide triphosphates, the building blocks of ribonucleic acid (RNA), was identified by researchers at the Institute of Science Tokyo. By using ...
