Nucleic Acid Heteroduplexes MeSH Descriptor Data 2023


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.
