DNA geometric change

Term Information

Accession
GO:0032392
Name
DNA geometric change
Ontology
biological_process
Synonyms
None
Alternate IDs
None
Definition
The process in which a transformation is induced in the geometry of a DNA double helix, resulting in a change in twist, writhe, or both, but with no change in linking number. Includes the unwinding of double-stranded DNA by helicases. Source: GOC:mah
Comment
Note that DNA geometric change and DNA topological change (GO:0006265) are distinct, but are usually coupled in vivo.
