Stabilization of linear double-stranded DNA in the presence of exonucleases

摘要

The present invention is directed at stabilizing linear polynucleotides against exonucleolytic attack. Adding to both ends of a double-stranded linear DNA a target sequence for a DNA-binding protein the double-stranded linear DNA with the two added target sequences has an increased stability against exonucleolytic attack when contacted with the DNA-binding protein.
