MeSH definition : A method of detecting gene mutation by mixing PCR-amplified mutant and wild-type DNA
followed by denaturation and reannealing. The resultant products are resolved by gel
electrophoresis, with single base substitutions detectable under optimal electrophoretic
conditions and gel formulations. Large base pair mismatches may also be analyzed by
using electron microscopy to visualize heteroduplex regions.;
