Metastable two-stranded DNA loops can be assembled into extended DNA oligomers by kinetically controlled self-assembly. Along the designed reaction pathway, the sequence of hybridization reactions is controlled by progressively revealing toeholds required to initiate strand-displacement reactions. The product length depends inversely on seed concentration and ranges from a few hundred to several thousand base-pairs.
亚稳态双链DNA环可通过动力学控制的自组装组装成延伸的DNA寡聚物。沿着设计的反应途径,杂交反应的顺序由逐步暴露引发链置换反应所需的链端来控制。产物长度与种子浓度成反比,范围从几百到几千个碱基对。
