For a face-on ellipsoid: $F_{\rm drag}^{\rm ellf}\simeq\frac{8\pi\eta a V}{\ln(2a/b)-0.5}$.\\  For a face-on cylinder: similar to the face-on ellipsoid, but slightly higher.\\  As expected, the face-on bodies (where the motion is perpendicular to the long axis) encounter more resistance to motion than the end-on bodies -- roughly twice as much, depending on the dimensions. Doesn't this mean that, in steady-state, all the DNA will move in the longitudinal direction?  \item Perhaps this is not a problem: we consider a low-Re regime, where viscous effects are much more important than inertia. Thus the instability or propensity to change orientation might not matter.  \end{itemize}  %%-------------------------------------------------
