  We analyze the governing partial differential equations of a model of
pole-to-pole oscillations of the MinD protein in a bacterial cell. The
sensitivity to extrinsic noise in the parameters of the model is explored. Our
analysis shows that overall, the oscillations are robust to extrinsic
perturbations in the sense that small perturbations in reaction coefficients
result in small differences in the frequency and in the amplitude. However, a
combination of analysis and simulation also reveals that the oscillations are
more sensitive to some extrinsic time-scales than to others.
