P.997 bottom paragraph to p.998 top paragraph: "Perspectives and Summary: Substantial progress has been made recently in understanding the unique physical features of double helical DNA and their implications for its interactions with ligands and for packaging DNA in vivo. These unique features of DNA include: 1. its lateral and torsional stiffness 2. its high axial charge density (two phosphate groups per 3.4Å) and moderate surface charge density (two phosphate groups per 210Å^2) and 3. its superposition of two binding lattices, one a relatively homogeneous array of phosphate charges that will interact electrostatically and nonspecifically with cationic ligands, the other a heterogeneous array of stacked base pairs that will interact with ligands nonelectrostatically and specifically."
