Optical melting measurements of nucleic acid thermodynamics. [PDF]
Methods Enzymol, 2009Optical melting experiments provide measurements of thermodynamic parameters for nucleic acids. These thermodynamic parameters are widely used in RNA structure prediction programs and DNA primer design software. This review briefly summarizes the theory and underlying assumptions of the method and provides practical details for instrument calibration ...

The Effect of Magnesium on the Thermodynamics of Nucleic Acid Tertiary Contact Formation [PDF]
Biophysical Journal, 2014Functional RNAs fold into compact, well-defined tertiary structures despite strong electrostatic repulsion both within and between helices. To achieve these compact structures, many RNAs employ structural divalent cations, typically Mg2+. The simplest tertiary contact in nucleic acids is two helices, joined by some non-helical contact.

What Controls the Hybridization Thermodynamics of Spherical Nucleic Acids?* [PDF]
Journal of the American Chemical Society, 2020The hybridization of free oligonucleotides to densely packed, oriented arrays of DNA modifying the surfaces of spherical nucleic acid (SNA)-gold nanoparticle conjugates occurs with negative cooperativity; i.e., each binding event destabilizes subsequent binding events. DNA hybridization is thus an ever-changing function of the number of strands already

Thermodynamics of force-dependent folding and unfolding of small protein and nucleic acid structures [PDF]
Integrative Biology, 2015In this paper, we outline the theoretical framework for understanding the equilibrium force-dependent folding and unfolding transitions of protein domains and small nucleic acid structures, both having small rigid folded structures and highly flexible ...
