A polynucleotide comprising a first region the 5′ end of which is complementary to a portion of a target nucleic acid, a cleavable second region, a third region having a stem-loop structure, and a fourth region complementary to the 3′ end of the first region, and use of the polynucleotide, as well as a composition comprising two such polynucleotides each of which hybridize different strands of a double-stranded target nucleic acid, and methods and kits using the same for amplifying targets. |
