Journal ArticleDOI
Driven polymer translocation through a narrow pore.
TL;DR: In this article, a polynucleotide is driven through a proteinaceous pore by an electric field, and the diffusive motion of a polymer threaded through a narrow channel with which it may have strong interactions is studied.
Journal ArticleDOI
Unzipping kinetics of double-stranded DNA in a nanopore.
TL;DR: Polymerase chain reaction analysis yielded the first direct proof of DNA unzipped in such a system, and the enthalpy barriers to unzipping and the effective charge of a nucleotide in the pore were considerably smaller than previously assumed.
Journal ArticleDOI
Driven Polymer Translocation Through a Narrow Pore
TL;DR: There is a range of polymer lengths in which the system is approximately translationally invariant, and a coarse-grained description of this regime is developed, and general features of the distribution of times for the polymer to pass through the pore may be deduced.
Journal ArticleDOI
Epithelial tricellular junctions act as interphase cell shape sensors to orient mitosis

TL;DR: In Drosophila epithelia, tricellular junctions (TCJs) localize force generators, pulling on astral microtubules and orienting cell division via the Dynein-associated protein Mud independently of the classical Pins/Gαi pathway, serving as polarity cues promoting geometry and mechanical sensing in epithelial tissues.
Journal ArticleDOI
Pulling pinned polymers and unzipping DNA.
TL;DR: For random DNA sequences with short-ranged correlations, exact results for the number of monomers liberated and the specific heat are obtained, including the critical behavior at the transition.
