Scientists Find All DNA and RNA Building Blocks in Meteorites, Hinting at Life’s Cosmic Origins
Scientists have uncovered compelling evidence that life’s essential ingredients may have arrived from space. For the first time, researchers have identified all the nucleobases—the molecular building blocks of DNA and RNA—in meteorites. This discovery strengthens the idea that some of life’s raw materials originated beyond Earth. Meteorites, which are fragments of asteroids or comets that […]
