摘要：
As genetic material DNA is wonderful, but as a macromolecule it is unruly, voluminous and fragile. Without the action of DNA replicases, topoisomerases, helicases, translocases and recombinases, the genome would collapse into a topologically entangled random coil that would be useless to the cell. We discuss the organization, movement and energetics of these proteins that are crucial to the preservation of a molecule that has such beautiful biological but challenging physical properties.
