DNA metastability and biological regulation: conformational dynamics of metastable omega-DNA bulge loops.

Abstract excerpt

Dynamic interchange between DNA conformations, including metastable states, can be of importance to biological function. In this study, we use a combination of spectroscopic and calorimetric techniques to detect and characterize kinetically trapped, metastable states in strand exchange and strand displacement reactions for bulge loop DNA conformations, here referred to as Omega-DNAs. We show that such metastable,...
