Single-Molecule Studies Of Local And Global Nucleic-Acid Dynamics, Eric Muthuri Patrick Jan 2013

Single-Molecule Studies Of Local And Global Nucleic-Acid Dynamics, Eric Muthuri Patrick

Wayne State University Dissertations

Nucleic acids undergo both global and local conformational changes that are important for their function. Structural studies have over the decades been invaluable in elucidation of various biomolecular mechanisms, hence contributing significantly to the understanding of biological events. However, a clear understanding of how molecules function in the cellular context requires investigation of their interconversion between multiple conformations, including mapping the folding landscape and any coupled changes in conformation. Work in this thesis focuses on fluorescence experiments, mainly at a single-molecule level to investigate such processes.

First, a novel single-molecule approach is described focusing on local dynamics within nucleic acids ...
