The Daniels distribution function, modified for excluded volume effects, is used to compute averages for scattering elements separated by contour lengths which are long with respect to the persistence length of the chain. An expansion in terms of exactly known moments of the distribution for the wormlike coil without excluded volume is used for short contour lengths. The results are applied to scattering from calf thymus (<jats:italic>M<\/jats:italic> = 18.1 \u00d7 10<jats:sup>6<\/jats:sup>) and T7 (<jats:italic>M<\/jats:italic> = 25.4 \u00d7 10<jats:sup>6<\/jats:sup>) DNA. It is demonstrated that the same values of excluded volume parameter (\u03b5 = 0.11) and statistical segment length (1\/\u03bb\u2032 = 900 \u00c5) which explain the sedimentation and viscosity behavior of DNA also account satisfactorily for the scattering behavior.
