Disclosed are vectors, kits and methods useful in the construction of recombinant cells and DNAs via enhanced efficiency homologous recombination. The vectors are targeting vectors that contain a gene-of-interest spliced between two ends that are homologous to a genome target site. The ends of the vector may be protected from exonuclease attack by deploying a cap, such as a hair pin structure. The vector is linked to a nuclear localization signal sequence, and preferably, a bait peptide that binds to RAD51, to facilitate homologous recombination. The vector may be deployed in myriad genetic transformation applications, such as site-directed mutagenesis, gene therapy, and the like.
