Stability and Sabotage: The Dual Chemical Nature of Life's Most Fundamental Nucleobase
Adenine occupies a paradoxical position in molecular biology: the very structural properties that make it ideal for encoding genetic information also render it surprisingly vulnerable to oxidative damage and spontaneous chemical alteration. New research is illuminating the evolutionary trade-offs embedded in adenine's chemistry, and scientists are beginning to exploit those trade-offs to develop more precise therapeutic strategies.
