Fluctuation-Facilitated Charge Migration along DNA
, 2000 We propose a model Hamiltonian for charge transfer along the DNA double helix with temperature driven fluctuations in the base pair positions acting as the rate limiting factor for charge transfer between neighboring base pairs.

Nucleic Acids Research, 2013 The p53 core domain binds to response elements (REs) that contain two continuous half-sites as a cooperative tetramer, but how p53 recognizes discontinuous REs is not well understood. Here we describe the crystal structure of the p53 core domain bound to

Statistical Theory of Force Induced Unzipping of DNA
, 2005 The unzipping transition under the influence of external force of a dsDNA molecule has been studied using the Peyrard-Bishop Hamiltonian. The critical force $F_c(T)$ is found to depend on the potential parameters $k$, represents the stiffness of single ...

Bubble generation in a twisted and bent DNA-like model [PDF]
, 2004 The DNA molecule is modeled by a parabola embedded chain with long-range interactions between twisted base pair dipoles. A mechanism for bubble generation is presented and investigated in two different configurations.

Nucleic Acids Research, 2013 The G:C reverse Watson–Crick (W:W trans) base pair, also known as Levitt base pair in the context of tRNAs, is a structurally and functionally important base pair that contributes to tertiary interactions joining distant domains in functional RNA ...

Chromatin Structure in the Cellular Slime Mold Dictyostelium discoideum [PDF]
, 1978 The structure of Dictyostelium discoideum chromatin has been studied by the following techniques: electron microscopy, staphylococcal nuclease digestion, acrylamide gel electrophoresis, sucrose gradient centrifugation, and melting.

Pair-Linking for Collective Entity Disambiguation: Two Could Be Better Than All
, 2018 Collective entity disambiguation aims to jointly resolve multiple mentions by linking them to their associated entities in a knowledge base. Previous works are primarily based on the underlying assumption that entities within the same document are highly

Frequency and isostericity of RNA base pairs [PDF]
Nucleic Acids Research, 2009 Most of the hairpin, internal and junction loops that appear single-stranded in standard RNA secondary structures form recurrent 3D motifs, where non-Watson-Crick base pairs play a central role. Non-Watson-Crick base pairs also play crucial roles in tertiary contacts in structured RNA molecules.

Molecules, 2012 Toward the expansion of the genetic alphabet, an unnatural base pair between 7-(2-thienyl)imidazo[4,5-b]pyridine (Ds) and pyrrole-2-carbaldehyde (Pa) functions as a third base pair in replication and transcription, and provides a useful tool for the site-

Biomechanics of DNA: rotational oscillations of bases [PDF]
Компьютерные исследования и моделирование, 2011 In this paper we study the rotational oscillations of the nitrous bases forming a central pair in a short DNA fragment consisting of three base pairs.
