Abstract
An intended nucleic acid is determined in a sample by a method in which at least one of the nucleic acid strands of the intended nucleic acid is subjected to hybridization with a primer and to chain-extension reaction over the primer to form a synthesized nucleic acid which is complementary to and in hybridization with the strand; a copy of the intended nucleic acid is obtained, which copy is (a) the nucleic acid of the double-stranded double produced by the chain-extension reaction, or (b) the synthesized nucleic acid freed from the double-stranded nucleic acid, or (c) a double stranded nucleic acid form from a pair of the synthesized nucleic acids complementary with each other; and it is determined whether the copy is present in the sample thereby to know whether the intended nucleic acid is in present in the sample.
