Structural Water of Nucleic Acids is only slightly perturbed, except for the structurally important water fraction around repetitive sequences (spines of A-T stretches), unusual conformations (phosphate-water-base bridges of . bases), or non-Watson-Crick base pairs (G-T, A-A, G-A,...).小画像 发表于 2025-3-28 21:47:35

Effect of Hydration and Metal Ions on DNA Conformations Studied by Vibrational Spectroscopyydrated films, crystals. It is therefore possible to study the effect of hydration on the geometry of a DNA sequence and investigate the existence of possible conformational transitions. Vibratioal spectroscopy is thus able to establish a relationship between the results obtained in solid state by X周兴旺 发表于 2025-3-29 05:28:48

Ionic Effects on DNA Electrostatic and Elastic Stability to be electrostatically more stable than the interwound form at low ionic strength. We define null DNA as a hypothetical form lacking phosphate charge and conclude by considerations of elastic instability that null DNA is curved (regardless of sequence).使成核 发表于 2025-3-29 14:37:48
