General description

This is a collection of protocols for investigating DNA structure, topology, and DNA topoisomerase function. These methods utilize new approaches to study changes in DNA topology (linking number, knotting, catenation, and relaxation) and DNA structure (bending), as well as to assess chromosome structure through FLP-mediated recombination and to analyze bacterial nucleoid structure. Protocols detail the expression and purification of bacterial, viral, and eukaryotic DNA topoisomerases.
