Resolve an exact external ontology class for DNase activity before adding a TraitRecord xref.

CURATION TODO OPEN dnase-activity-xref-gap · raised by codex · 2026-09-11

Not yet attached to a section of this record — a curator sets attaches_to (e.g. causal_graphs#some_edge) so the gap shows beside the mechanism it concerns.

GO:0004536 denotes the DNA nuclease molecular function rather than the organism-level DNase production phenotype, so it is too scope-shifted for an equivalent TraitRecord xref.
