[主題詞] Nucleic Acid Heteroduplexes
[英文釋義] 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.
