  The present invention relates to a method for nucleic acid replication and novel artificial base pairs. The method of the present invention for nucleic acid replication is characterized in that a deoxyribonucleoside 5′-triphosphate, in which the hydroxyl group of phosphoric acid at the γ-position is substituted with a group selected from the group consisting of an amino group, a methylamino group, a dimethylamino group, a mercapto group and a fluoro group, is used as a substrate during replication reaction. The novel artificial base pairs of the present invention are characterized in that 7-(2-thienyl)-imidazo[4,5-b]pyridine (Ds) or an analog thereof forms a base pair with pyrrole-2-carbaldehyde (Pa) or an analog thereof.

  The present invention is to provide a method for analyzing a target nucleic acid, by which the target nucleic acid can be analyzed rapidly and easily. In order to achieve the above object, the present invention provides a method for analyzing a target nucleic acid in a sample, including the step of: analyzing the target nucleic acid in the sample by bringing the sample into contact with a label and with a primer or probe that can hybridize to the target nucleic acid. The primer or probe is immobilized on a solid phase. The label does not emit light when the primer or probe does not hybridize to the target nucleic acid, whereas the label emits light when the primer or probe has hybridized to the target nucleic acid. The analysis is carried out by detecting the light emitted from the label.
