The method determines the bond caused at the previously determined site when the detection is carried out under a condition under which the nucleic acid of the detection object binds to the nucleic acid analogue by using the carrier. The method for selectively detecting a nucleic acid variant in the presence of large excess of nonmutated nucleic acid involves using the carrier and determining the bond of the mutated nucleic acid and/or nonmutated nucleic acid at different sites. The method for determining the nucleic acid involves using the carrier and determining the relative amounts of the mutated nucleic acid and the normal nucleic acid by comparing bound mutated nucleic acid and nonmutated nucleic acid.  <P>COPYRIGHT: (C)2004,JPO
