DNA Dynamics in Strongly Interacting Solutions

这个提议的目的是为了理解 生物聚合电解质，尤其是DNA， 互动解决方案 相互作用可以是静电的， 排除体积、缠结或某种组合。 等 条件是细胞内的规范。 这项工作使用准弹性 光散射（QLS）、强迫瑞利散射（FRS），以及 小角X射线散射（SAXS）揭示了 相互作用影响的扩散和结合行为， 生物聚合物 这种影响可能会产生重大影响， 生理相关条件。

The goal of this proposal is to understand the dynamical behavior of biological polyelectrolytes, especially DNA, in strongly interacting solutions. the interactions may be electrostatic, excluded volume, entanglement, or some combination. Such conditions are the norms inside cells. The work uses quasielastic light scattering (QLS), forced Rayleigh scattering (FRS), and small-angle x-ray scattering (SAXS) to shed light on how interactions influence the diffusional and binding behavior of biopolymers. Such influence can have major effects under physiologically relevant conditions.
