Two relaxation modes are revealed that can be attributed to diffusive motion of DNA counterions. The overall study in the wide concentration, added salt and chain length range demonstrates that the motion detected at lower frequencies probes single-chain structural properties, whereas the one at higher frequencies characterizes the collectives properties of the DNA solution composed of many chains. The characteristic length scales found in the measurements are compared with the fundamental length scales predicted by the theory. The issue of respective roles in ionic screening of intrinsic DNA counterions and added salt ions is also addressed with special emphasis on the controversial subject of DNA conformation in pure water solutions. At the end, open issues and prospects for further research are designated. ц ∙ hD$СhD$Сц ¤ц ¤,1Рh░В. ░╞A!░Й"░Й#РЙ$РЙ%░░─░─ Р─ЖЬ@@ё @ NormalCJ_HaJmH sH tHDA@Є бD Default Paragraph FontRi@є │R  Table NormalЎ4╓ l4╓aЎ (kЇ ┴(No Listц    шШ0ААц ц ц шшшхD$С @Ахх╠.КММххцp@  Unknown            GРюЗz А Times New Roman5РАSymbol3&Рю Зz А Arial"1ИЁ─ййC┼ЖйC┼ЖФRФR▒ЁЙЙ┤┤ББr4хх2ГQЁHP)Ё ?т                     D$С2  пA detailed characterization of complex dielectric response of Na-DNA aqueous solutions by means of dielectric spectroscopy in the frequency range 100 Hz  100 MHz is presentedstomicstomic■ рЕЯЄ∙OhлС+'│┘0РШP\lxДШ и┤ ╘ р ь°т░A detailed characterization of complex dielectric response of Na-DNA aqueous solutions by means of dielectric spectroscopy in the frequency range 100 Hz Ц 100 MHz is presentedstomic Normal.dotstomic1Microsoft Office Word@@╓╤─▒╚@╓╤─▒╚ФR■ ╒═╒Ь.УЧ+,∙о0Ш hp|ДМФ Ьдм┤ ╝ xтIFхи ░A detailed characterization of complex dielectric response of Na-DNA aqueous solutions by means of dielectric spectroscopy in the frequency range 100 Hz Ц 100 MHz is presented Title ■    ■   ■    !■   #$%&'()■   ¤   ,■   ■   ■                                                                                                                                                                                                                                                                                                                                       Root Entry         └F@И>у▒╚.АData              1Table    WordDocument    .SummaryInformation(            DocumentSummaryInformation8        "CompObj            q            ■                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           ■       └FMicrosoft Office Word Document MSWordDocWord.Document.8Ї9▓q
