Physics of Fluids, 2014
Supercoiling is the large-scale secondary coiling or buckling of a structure that is already coiled at a smaller scale. Here, we show experimentally that a fluid-mechanical analog of supercoiling can occur when a thin “rope” of viscous fluid falls vertically from a great height onto a surface. For appropriate values of the viscosity ν, the flow rate Q,

Supercoiling-Induced DNA Bending
Biochemistry, 2004Local DNA bending is a critical factor for numerous DNA functions including recognition of DNA by sequence-specific regulatory binding proteins. Negative DNA supercoiling increases both local and global DNA dynamics, and this dynamic flexibility can facilitate the formation of DNA-protein complexes. We have recently shown that apexes of supercoiled DNA

Abstract In the first chapter, we described the classical double-helical structure of DNA, and the local alterations of that structure that can occur as a consequence of specific nucleotide sequences. We hope you now have a good feel for these concepts, and we will move on to the main subject of this book, the supercoiling of DNA, a ...

Watching Supercoiled DNA The DNA double helix can undergo additional twisting, or supercoiling, that plays a role in transciption and protein binding, in part by bringing distant DNA locations together.
