<p>A method whereby a mismatched base pair in a nucleic acid such as DNA or RNA can be conveniently and highly sensitively detected; and detection reagents therefor. A method comprising, in a base pair failing to form a normal base pair, forming a mimetic base pair with the use of a mismatch-recognizing molecule represented by the following general formula (I): A-L-B (I) wherein A represents a chemical structure moiety capable of forming a pair with one of the bases of the base pair failing to form a normal base pair; B represents a chemical structure moiety capable of forming a pair with the other of the bases of the base pair failing to form a normal base pair; and L represents a linker structure whereby the chemical structure moieties A and B are linked to each other; and measuring the formation of the above-described mimetic base pair to thereby detect and identify the base pair failing to form a normal base pair; kits therefor; reagents for detecting a mismatch; and a method of detecting an abnormality in the base sequence of a gene.</p> |
