Single-molecule and bulk biophysical approaches to study protein-DNA interactions on surface-immobilized nucleic acid templates typically rely on modifying the ends of linear DNA molecules to enable surface-DNA attachments. Unless both strands are constrained. this results in topologically free DNA molecules and the inability to observe supercoiling-dependent biological processes or r... https://www.roneverhart.com/5-5-Parlor-Palm-Artificial-Tree-in-White-Tower-Planter/
