Scientists have discovered all five essential nucleobases used in DNA and RNA in pristine samples from asteroid Ryugu, revealing that key ingredients for life existed in space billions of years ago. The remarkable finding adds to growing evidence from other asteroids and meteorit
Scientists have discovered all five essential nucleobases used in DNA and RNA in pristine samples from asteroid Ryugu, revealing that key ingredients for life existed in space billions of years ago. The remarkable finding adds to growing evidence from other asteroids and meteorites that these molecules were widespread throughout the early Solar System.
