New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...

The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead ...

Chemists at University College London have shown how two of biology's most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of ...

RNA probably came before DNA, serving as the storehouse of genetic information and driving chemical reactions; a ...
