Table 5. Mutation or RNAi of the C. elegans ensa-1 gene causes slight delays in AB and P1 cell cycles.

Genotype	AB cell-cycle time, min ± SD.	P1 cell-cycle time, min ± SD.	N
N2 (wild type)	15.35 ± 0.24	17.30 ± 0.28	12
N2, control RNAi	15.07 ± 0.30	17.18 ± 0.38	11
ensa-1(tm2810)	16.31 ± 0.61*	18.60 ± 0.83*	17
ensa-1(RNAi)	16.10 ± 0.26*	18.34 ± 0.26*	9
ensa-1(tm2810)/qDf9	17.62 ± 0.19*	20.23 ± 0.30*	10

AB and P1 cell-cycle times were measured from P0 NEBD to AB or P1 NEBD. (*) P < 2.0E-05; T-test to N2.
