Title: PHYSICS OF DNA

Abstract:

I will present two cases of scattering in DNA solutions. First the standard X-ray scattering of DNA and the famous Photo 51 of Rosalind Franklin with the elucidation of its double helical structure and then the light scattering with the first measurement of the DNA persistence length. We will see how different scales of the DNA description bring fourth its different microscale and mesoscale properties. After that I will give an overview of the very unusual electrostatics of DNA and the phenomenon of DNA condensation.
