"Rule of thumb" for DNA charge density

Value ~6 e/nm
Organism Unspecified
Reference "Physical Biology of the Cell", Rob Phillips, Jane Kondev and Julie Theriot (2009). Page 26
Method e=elementary charge (1.602176487(40)×10^-19Coulombs). the charge on a single electron or proton.
Comments The linear, surface, or volume charge density is the amount of electric charge in a line, surface, or volume. This value is derived from two phosphate groups, each having an elementary charge e for length of each base pair of DNA 0.34 nm. 2/0.34=5.88e/nm
