While mutations in <i>dop-1</i> fail to suppress <i>dop-3</i> speed fluctuations, <i>dop-3</i> genomic constructs do, regardless of the promoter used.

<p>The average standard deviations of speed measurements within individual tracks for (A) wild-type animals, mutant animals, and (B) transgenic strains on a bacterial lawn. p-values for differences between standard deviation curves for each genotype were calculated using two-way ANOVA. Tracks were first grouped by average speed. Error bars, SEMs. (A: wild-type n = 934 tracks; <i>dop-3(vs106)</i> n = 941; <i>dop-1(vs100)</i> n = 1045; <i>dop-1(vs100) dop-3(vs106)</i> n = 887. B: wild-type n = 934 tracks, <i>dop-3</i> cDNA transgenic n = 853, <i>dop-3</i> genomic transgenic n = 861, P<i>_{unc-17::dop-3}</i> genomic transgenic n = 791, P<i>_unc-47dop-3</i> genomic transgenic n = 911, P<i>_tax-4::dop-3</i> genomic transgenic n = 1005, P<i>_gcy-5::dop-3</i> genomic transgenic n = 917. all tracks >30 sec).
