Abstract
Cyanogen bromide was found to induce a smooth and highly efficient condensation of oligonucleotide blocks within DNA duplexes. This template-directed reaction proceeds in the aqueous solution at 0.degree. C for 1-2 min. Cyanogen bromide catalyzes the formation not only of phosphodiester, but also of unnatural phosphoramide and pyrophosphate interoligomer bonds.
