Stretching, Twisting and Supercoiling in Short, Single DNA Molecules
Pui-Man Lam, Yi Zhen
We had combined the Neukirch-Marko model that describes the extension, torque and supercoiling in single, stretched and twisted DNA of infinite contour length, with a form of the f…
Cyclization of Short DNA Fragments
Pui-Man Lam, Yi Zhen
From the per unit length free energy for DNA under tension, we have calculated an effective contour length dependent persistence length for short DNA. This effective persistence le…
Extension, Torque and Supercoiling in Single, Stretched and Twisted DNA Molecules
Pui-Man Lam, Yi Zhen
We reinvestigate the model originally studied by Neukirch and Marko that describes the extension, torque and supercoiling in single, stretched and twisted DNA molecules, which cons…
Dynamic scaling theory of the forced translocation of a semi-flexible polymer through a nanopore
Pui-Man Lam, Yi Zhen
We present a theoretical description of the dynamics of a semi-flexible polymer being pulled through a nanopore by an external force acting at the pore. Our theory is based on the…
Worm-Like-Chain Model of Forced Desorption of a Polymer Adsorbed on an Attractive Wall
Pui-Man Lam, Yi Zhen
Forced desorption of a semiflexible polymer chain on a solid substrate is theoretically investigated. The pulling force versus displacement is studied for different adsorption ener…
The Role of Chain Entropy in an Analytic Model of Protein Binding in Single-DNA Stretching Experiments
Pui-Man Lam, Richard M. Neumann
We show that the simple analytical model proposed by Zhang and Marko (Phys. Rev. E 77, 031916 (2008)) to illustrate Maxwell relations for single-DNA experiments can be improved by…
