New Experiments Strengthen RNA World Theory on the Origin of Life
What the RNA World Hypothesis Proposes The RNA world hypothesis suggests that life began with RNA molecules capable of storing genetic information and catalyzing chemical reactions. Long before DNA and proteins dominated biology, RNA could have served as both information carrier and catalyst, enabling the first self-replicating systems. This scenario helps explain how early life…
