A method for detecting a mismatch between a target nucleic acid as a measuring obj ect and a control nucleic acid, the method comprising: (a) effecting formation of a double-stranded nucleic acid through hybridization of the control nucleic acid and the target nucleic acid; (b) allowing a mismatch binding protein to contact with the double-stranded nucleic acid and thereby to bind to a mismatched site; (c) allowing an intercalating agent which specifically recognizes the double-stranded nucleic acid and is intercalated therein, to contact with the double-stranded nucleic acid; (d) detecting the intercalating agent intercalated into the double-stranded nucleic acid; and (e) judging the presence or absence of a mismatch between the control nucleic acid and the target nucleic acid, by comparing amounts of the intercalating agent intercalated into the double-stranded nucleic acid in the absence and presence of the mismatch binding protein.
