ABSTRACT:
The present invention provides methods, nucleic acid constructs, and kits for selectively deleting a region of a nucleic acid sequence. Specifically, it utilizes retargeting retroelements to place site-specific recombination sites at targeted locations in the nucleic acid sequence. The region between the recombination sites is then deleted using a site-specific recombination system.
