Chiral elasticity of DNA
DNA has been described as a semiflexible polymer. But DNA is chiral, so its bending Hamiltonian contains nonlinear terms coupling the curvature κ to the torsion τ , leading to an average 〈τ〉 independent of κ, and variance 〈∆τ〉 scaling as 1/κ. We perform atomistic MD simulations of 31 base-pair DNA sequences with explicit solvent, in which “restraints” are imposed to “encourage” the DNA to bend....
متن کاملHybridization-sensitive fluorescent DNA probe with self-avoidance ability.
Hybridization-sensitive fluorescent probes have an inherent disadvantage: self-dimerization of the probe prevents the fluorescence quenching prior to hybridization with the target, resulting in a high background signal. To avoid self-dimerization of probes, we focused on a base pair formed by 2'-deoxyinosine (I) and N(4)-ethyl-2'-deoxycytidine (E). I and E bases form more stable base pairs with...
متن کاملTwist-Stretch Elasticity of DNA
The symmetries of the DNA double helix require a new term in its linear response to stress: the coupling between twist and stretch. Recent experiments with torsionally-constrained single molecules give the first direct measurement of this important material parameter. We extract its value from a recent experiment of Strick, et al. and find rough agreement with an independent experimental estima...
متن کاملSequence Dependent Elasticity of DNA
The DNA contained in every living cell not only stores the genetic information; it functions in a complex molecular network that can condense, transcribe, replicate and repair genes. The essential role played by the sequence dependent structure and deformability of DNA in these basic processes of life, has received increasing attention over the past years. The present work aims at better unders...
متن کاملTopology agnostic hot-spot avoidance with InfiniBand
InfiniBand has become a very popular interconnect, due to its advanced features and open standard. Large scale InfiniBand clusters are becoming very popular, as reflected by the TOP 500 supercomputer rankings. However, even with popular topologies like constant bi-section bandwidth Fat Tree, hot-spots may occur with InfiniBand, due to inappropriate configuration of network paths, presence of ot...
