MeSH definition : The presence of an uncomplimentary base in double-stranded DNA caused by spontaneous
deamination of cytosine or adenine, mismatching during homologous recombination, or
errors in DNA replication. Multiple, sequential base pair mismatches lead to formation
of heteroduplex DNA; (NUCLEIC ACID HETERODUPLEXES).;
MeSH synonym : base pair mismatches; mismatch, base pair; mismatches, base pair;
