Molecular Structure of Deoxypentose Nucleic Acids
While the biological properties of deoxypentose nucleic acid suggest a molecular structure containing great complexity, X-ray diffraction studies described here show the basic molecular configuration has great simplicity. The purpose of this communication is to describe, in a preliminary way, some of the experimental evidence for the polynucleotide chain configuration being helical , and existing in this form when in the natural state. A fuller account of the work will be published shortly.
The structure of deoxypentose nucleic acid is the same in all species (although the nitrogen base ratios alter considerably)in nucleoprotein, extracted or in cell, and in purified nucleate. The same linear group of polynucleotide chains may pack together parallel or paracrystalline material.In all cases the x-ray diffraction photograph consists of two regions, one determined largely by the regular spacing of nucleotides
