MeSH definition : 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.;
