Abstract
The concentrated solutions of sodium salt of deoxyribonucleic acid have been observed under crossed polaroids and tested by means of the small-angle laser light scattering, the ultraviolet and infrared absorptions, the X-ray diffraction, the circular dichroism, and some other physical methods. The molecules of this poly-nucleotide aggregate to form rod-like assemblies (molecular clusters) at a certain polymer concentration and eventually form liquid crystalline structures. These liquid crystals are very similar to those found in the concentrated aqueous solutions of deoxygenated sickle-cell hemoglobin or of sodium salt of poly(glutamic acid).
