Fig. 2

Here, the polymer has 5 monomers and the Péclet number is Pe = 50. Further, τ0 denotes the diffusion time, \({\tau }_{\,{{{{\mbox{rot}}}}}\,}^{0}\) the rotational relaxation time of a non-tumbling polymer, τdiff the cross-over time between short-time diffusion and directed swimming motion, and L the polymer length. The colored triangles indicate the characteristic time of tumbling, 1/λ divided by τ0, for different reversal rates. Source data are provided as a Source Data file.
