| Name | DNA geometric change |
| ID | GO_0032392 |
| collection_id | Biological process |
| Description | 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. |
| Comment | Note that DNA geometric change and DNA topological change (GO:0006265) are distinct, but are usually coupled in vivo. |
