Abstract
A GREAT amount of research work concerning the study of the molecular characteristics of a deoxyribonucleic acid from various sources has been carried out in the past few years. Generally, cell nuclei, bacteria or phages are treated by a proper method the result of which is to obtain the deoxyribonucleic acid particles in a suitable solution. It is then possible to precipitate the acid from this solution, to stretch fibres of it, and study its X-ray diagram. Furthermore, one can determine the molecular weight and radius of gyration of the particles in solution through light-scattering measurements.
