Nucleic Acid Heteroduplexes MeSH Descriptor Data 2026


MeSH Heading
Nucleic Acid Heteroduplexes
Tree Number(s)
D13.444.500
Unique ID
D009692
RDF Unique Identifier
http://id.nlm.nih.gov/mesh/D009692
Annotation
coord with specific DNA or RNA or both (IM)
Scope Note
Double-stranded nucleic acid molecules (DNA-DNA or DNA-RNA) which contain regions of nucleotide mismatches (non-complementary). In vivo, these heteroduplexes can result from mutation or genetic recombination; in vitro, they are formed by nucleic acid hybridization. Electron microscopic analysis of the resulting heteroduplexes facilitates the mapping of regions of base sequence homology of nucleic acids.
Entry Term(s)

Heteroduplexes, Nucleic Acid
