Populations and Dynamics of Guanine Radicals in DNA strands—Direct versus Indirect Generation

Populations and Dynamics of Guanine Radicals in DNA strands—Direct versus Indirect Generation

Guanine radicals, known to be involved in the damage of the genetic code and aging, are studied by nanosecond transient absorption spectroscopy. They are generated in single, double and four-stranded structures (<b>G</b>-quadruplexes) by one and two-photon ionization at 266 nm, correspon...
