Graphical Abstract

Stability: A modified nucleoside triphosphate is incorporated into DNA sequences using polymerase. The resulting photocaged DNA is resistant against cleavage by restriction endonucleases (REs) and fully replicable by polymerase chain reaction (PCR) or primer extension (PEX).

Abstract

5-[(2-Nitrobenzyl)oxymethyl]-2′-deoxyuridine 5′-O-triphosphate was used for polymerase (primer extension or PCR) synthesis of photocaged DNA that is resistant to the cleavage by restriction endonucleases. Photodeprotection of the caged DNA released 5-hydroxymethyluracil-modified nucleic acids, which were fully recognized and cleaved by restriction enzymes.
