DAG for GO:0006265id: GO:0006265

name: DNA topological change
namespace: biological_process
def: "The process in which a transformation is induced in the topological structure of a double-stranded DNA helix, resulting in a change in linking number." [ISBN:071673706X, ISBN:0935702490]
comment: Note that the synonym 'DNA underwinding' should not be confused with 'DNA unwinding ; GO:0006268', which refers to DNA strand separation, and is a type of geometric change. GO:0006265 refers to alteration of the superhelical density of double-stranded DNA. Note that DNA topological change and DNA geometric change (GO:0032392) are distinct, but are usually coupled in vivo.
