Claim Text:
1. A nucleic acid gel composition comprising a mixture of two or more oligonucleotides composed of a cohesive protruding end moiety and a complementary base sequence moiety in the composition at a nucleic acid concentration of 3.2/x mM or more and containing a salt at a concentration of 640 mM/x-60 mM or more in terms of a NaCl concentration, wherein the nucleic acid gel composition does not contain a nucleic acid linking enzyme, and wherein x is the number of bases in the protruding end moiety, the cohesive protruding end moiety is a single strand nucleic acid moiety having 4 or more nucleotide length and being complementary to a cohesive protruding end moiety in at least one other oligonucleotide to such a degree as to form a double strand sequence showing a melting temperature that is equal to or higher than the body temperature in a physiological condition, and the complementary base sequence moiety that binds to the other oligonucleotide in a complementary manner has 8 or more nucleotide length and is complementary to the complementary base sequence moiety in the other oligonucleotide to such a degree as to form a double strand sequence showing a melting temperature that is equal to or higher than the body temperature in a physiological condition.
