Phosphorylation

3’—Phosphorylation. Chemical 3’-phosphorylation is used to block oligonucleotide elongation by DNA polymerases lacking 3’→5’ exonuclease activity.

5’-Phosphorylation. Chemical 5’-phosphorylation is an efficient alternative to enzymatic procedures that simplify a working layout and save time. 5’-Phophorylated oligonucleotides are used in gene assembly, ligase chain reaction and construction of DNA nanostructures [DOI: 10.1039/C8CC00738A].

Available sites for modifications are 5 and 3’.>
