SITE-SPECIFIC DYNAMICS IN DNA:Experiments

This chapter reviews the dynamics information obtained from experimental magnetic resonance studies of site-specifically labeled duplex DNA. A previous review (43) discusses the dynamics of duplex DNA; it develops a theory that shows how magnetic resonance experiments are used to detect those dynamics. The methods for obtaining information about dynamics as well as a summary of what is now known about the site-specific dynamics of DNA are presented. This review contains two methods sections which present results using electron paramagnetic resonance and nuclear magnetic resonance active probes.
