DATABASE_MATCH via CultureMech

Imported from CultureMech pipeline, quality=DIRECT_MATCH

DATABASE_MATCH via MIM curation (#322)

mapping_quality EXACT_MATCH -> NARROW_MATCH. CHEBI:16991 carries no structural definition, so it is a class rather than an individual, and the record's label 'Fish-Sperm DNA' does not equal the term label 'deoxyribonucleic acid'. EXACT_MATCH therefore asserted an identity the pair does not have. Re-graded because source-qualified: the term is DNA generally.

The record is narrower than CHEBI:16991 (source-, form- or scope-qualified), and §3 forbids expressing a more specific thing by sharing a broader term's identifier. Minted per step 3. (#322) Required by SSSOM Rule B1 once the mapping was re-graded to narrow/broad.
