Our work presents new findings about the DD structural dynamics, mechanical properties, and the coupling between basepair and backbone configurations, including their statistical reliability. The basic structural parameters converge very well within 300 ns, convergence of the BI/BII populations and stiffness matrices is less sharp. The Riemann distance and Kullback-Leibler divergence are used for stiffness matrix comparison. The nonlocal stiffness matrices for a rigid-base mechanical model of DD are reported for the first time, suggesting salient stiffness features of the central A-tract. For a given end pairing, distributions of the basepair step coordinates can be decomposed into Gaussian-like components associated with the BI/BII backbone states.

A clear relationship between the BI/BII backbone substates and the basepair step conformation has been identified, extending previous findings and exposing an interesting structural polymorphism in the helix. In the simulations, the duplex ends can adopt an alternative base-pairing, which influences the oligomer structure. I have countless women in my life who prove that every day. A woman’s age doesnt define her either personally or professionally. This week, Mick welcomes director, screenwriter and cinematographer Ernest Dickerson (TALES FROM THE CRYPT: DEMON KNIGHT, DEXTER, SURVIVING THE GAME) to. The 0.6-2.4-µs-long MD trajectories are compared to modern crystallographic and NMR data. The reference I made to a woman’s prime this morning was inartful and irrelevant, as colleagues and loved ones have pointed out, and I regret it. Here, we present an analysis of DD properties based on extensive atomistic molecular dynamics (MD) simulations using different ionic conditions and water models. The Dickerson-Drew dodecamer (DD) d- 2 is a prototypic B-DNA molecule whose sequence-specific structure and dynamics have been investigated by many experimental and computational studies.
