Tiny Chemical Difference Between RNA and DNA May Explain Life's Origin
Original: A Tiny Chemical Difference Between RNA and DNA May Help Explain How Life Began
Scientists are highlighting a subtle chemical distinction between RNA and DNA that could shed light on how life first emerged on Earth. The difference may explain why RNA, not DNA, likely served as the earliest genetic material, a central idea in origin-of-life research. The finding is being picked up by science news outlets and is prompting renewed discussion about the RNA world hypothesis.
Why now: New attention on origin-of-life research and the RNA world hypothesis following coverage of this chemical distinction.
