== Publication Abstract from PubMed ==
&lt;p class="Text" style="margin: 0in 0in 8pt; text-align: justify; line-height: 24px; font-size: 12pt; font-family: &quot;Times New Roman&quot;, serif; color: rgb(0, 0, 0);"&gt;Non-canonical interactions in DNA remain under-explored in DNA nanotechnology. Recently, many structures with non-canonical motifs have been discovered, notably a hexagonal arrangement of typically rhombohedral DNA tensegrity triangles that forms through non-canonical sticky end interactions. Here, we find a series of mechanisms to program a hexagonal arrangement using: the sticky end sequence; triangle edge torsional stress; and crystallization condition. We showcase cross-talking between Watson-Crick and non-canonical sticky ends in which the ratio between the two dictates segregation by crystal forms or combination into composite crystals. Finally, we develop a method for reconfiguring the long-range geometry of formed crystals from rhombohedral to hexagonal and &lt;italic&gt;vice versa&lt;/italic&gt;. These data demonstrate fine control over non-canonical motifs and their topological self-assembly. This will vastly increase the programmability, functionality, and versatility of rationally designed DNA constructs.&lt;o:p&gt;&lt;/o:p&gt;&lt;/p&gt;.
