New study brings scientists closer to the origin of RNA
December 23, 2013
One of the biggest questions in science is how life arose from the chemical soup that existed on early Earth. One theory is that RNA, a close relative of DNA, was the first genetic molecule to arise around 4 billion years ago, but in a primitive form that later evolved into today's RNA and DNA molecules. New research shows one way this chain of events might have started.
