Displacement distributions of RNA-protein particles in E. coli. (a) Ensemble of 1D displacement (Δx) distributions over multiple timescales (δ) along the long axis of E. coli. (b) Ensemble of 1D displacement distributions (Δx and Δy combined) over multiple timescales (δ) in the S. cerevisiae cytoplasm. (c and d) Same as (a) and (b), but with each displacement distribution rescaled by its standard deviation σ_δ for direct comparison to Laplace and Gaussian distributions. Particle displacement measurements for E. coli are from two different data sets spanning 1–100 s used for δ = 1 s and 10 s (this study) and 1–136 min used for δ = 2 min and 17 min (from Stylianidou et al. (14)). Particle displacement measurements for S. cerevisiae are from a single data set spanning 0.015–45 s (from Thompson et al. (32)). To see this figure in color, go online.
