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 includes compositions and methods of selecting functional genetic elements that includes selecting in vivo an autogene operon with one or more mutagenized functional genetic elements and one or more selectable elements, wherein survival of the autogene depends on expression of the one or more mutagenized functional genetic elements and one or more selectable elements.
