Writhe distribution of stiff biopolymers

Physical Review E, 2008
Motivated by the interest in the role of stiff polymers like actin in cellular processes and as components of biopolymer networks like the cytoskeleton, we present a statistical mechanical study of the twist elasticity of stiff polymers. We obtain simple, approximate analytical forms for the writhe distribution at zero applied force.

DNA Transcription: Keeping the writhe

Current Biology, 1994
A new model system has been used to demonstrate how a nucleosome may remain associated with an actively transcribed gene and yet maintain DNA compaction during transcription.

The Writhing Laocoön

Abstract This chapter examines Susan Sontag’s engagement with Greco-Roman texts, images, and artefacts in her seminal work, Regarding the Pain of Others (2003). Through an exploration of the dynamic interplay between ancient works, encompassing those by Homer, Aeschylus, Plato, and Aristotle, and the discourse surrounding modern war ...

Computing the writhe on lattices

Journal of Physics A: Mathematical and General, 2006
Given a polygonal closed curve on a lattice or space group, we describe a method for computing the writhe of the curve as the average of weighted projected writhing numbers of the polygon in a few directions. These directions are determined by the lattice geometry, the weights are determined by areas of regions on the unit 2-sphere, and the regions are

Link, Writhe, and Twist

2017
We review the concepts of writhe, twist, and linking as applied to space curves and ribbons. The application of these concepts to DNA is also discussed.
