Control of A Double Helix DNA Assembly by Use of Cross-Linked Oligonucleotides

Abstract
Disulfide cross-linked oligonucleotides for connecting two DNA double helixes have been designed, synthesized, and characterized. Employing these cross-linked oligonucleotides, two double helixes can be arranged side by side, and the orientations can be controlled both in parallel and antiparallel ways by addition of a specific complementary DNA strand.
