It's Surprisingly Easy To Brew Something Like RNA In A Puddle
Common chemicals turn into something a lot like RNA if you leave them alone in water, giving new clues to the origins of life on Earth.By Steven Sparkman | April 25, 2016
One of the biggest mysteries in science is how you could get life in a place where it doesn't already exist. Scientists have found some clues, though.
The latest is that Georgia Tech chemist Nicholas Hud was able to create something that looks a lot like RNA — a relative of DNA — using ingredients that would have been common on Earth when it was 4 billion years younger.
The study used two common chemicals left alone in what amounts to a mud puddle. The chemicals synced up and started forming that twisting ladder shape we think of when we picture DNA.
