Linear
DNA with improved resistance against exonucleases and methods for its production. The present invention relates to methods for producing a linear deoxyribonucleic acid (
DNA) product (e.g., a closed linear
DNA product) with improved resistance to
nuclease digestion. The present invention relates to methods comprising the steps of: (a) contacting a double-stranded DNA molecule with an
endonuclease, a ligase, and first and second terminal adaptor molecules and intermediate adaptor molecules to form a single contiguous aqueous volume; and (b) incubating the single contiguous aqueous volume to generate a linear DNA product (e.g., a closed linear DNA product). The present invention also relates to linear deoxyribonucleic acid (DNA) products (e.g., a closed linear DNA product) with improved resistance to
nuclease digestion and uses thereof.
