<P>PROBLEM TO BE SOLVED: To provide a means for simply detecting and/or elongating a nucleic acid chain in high sensitivity. <P>SOLUTION: The nucleic acid fragment is a nucleic acid fragment which is hybridized with a target nucleic acid containing a first target sequence x1 and a second target sequence x2 and comprises a sequence X1 complementary to the target sequence x1, a sequence Y, a sequence Z, a sequence y complementary to the sequence Y and a sequence X2 complementary to the target sequence x2 and is represented by X1-Y-Z-y-X2. <P>COPYRIGHT: (C)2004,JPO |
