||p.240 left column 4th paragraph:"Depending on the probability of anterograde runs, the drift velocity can be anywhere between zero (for equal probabilities) or ∼1 µm/s (the typical speed of a plus-end directed motor, which will be the effective speed of mRNPs [messenger ribonucleoproteins] if no retrograde runs occur). Measurements in Drosophila embryos reported a net mRNA velocity of 0.1 µm/s (primary source), suggesting that for these mRNPs the probability of anterograde runs is 55%."
