Ethanol-induced condensation of calf thymus DNA studied by laser light scattering
Article Abstract:
Experiments were conducted to study the effects of ethanol on DNA phosphate charge neutralization and condensation of DNA molecules. Findings have indicated that the hydrodynamic radius R (sub h) and the radius of gyration R (sub g) are clear indicators of changing condensation behavior. At low alcohol concentrations, the Gaussian coil exhibited an abrupt shape transition at 40% ethanol concentration. The Gaussian chain behavior manifested anew when the alcohol concentration was raised.
