Book excerpt: For decades, scientists from every discipline have struggled to understand the mechanism of biological self-assembly, which allows proteins and nucleic acids to fold reliably into functional three-dimensional structures. Such an understanding may hold the key to eliminating diseases such as Alzheimer's and Parkinson's and to effective protein engineering. The current best framework for describing biological folding processes is that of statistical mechanical energy landscape theory, and one of the most promising experimental techniques for exploring molecular energy landscapes is single molecule force spectroscopy (SMFS), in which molecules are mechanically denatured. Theoretical advances have enabled the extraction of complete energy landscape profiles from SMFS data. Here, SMFS experiments performed using laser optical tweezers are analyzed to yield the first ever full landscape profile for an RNA pseudoknot. Further, a promising novel landscape reconstruction technique is validated for the first time using experimental data from a DNA hairpin.
