Crawl movie
Fly-in movie
Male, scanning em
Male tail scanning em
Rene Mating Movie
Embryonic cell lineage
D lineage
ABala lineage
AIML neuron
AIML lineage
AIML circuit
Z1Z2 Z3 Z4
Postembryonic blast cells
Adult hermaphrodite anatomy
C. elegans typical cross section
Seam cell postembryonic lineages in the male
wild type
lin-4(e912) reiterations
wild type
lin-14(sd) repeats S1
lin-14(lf) skips S1
lin-4(e912) lin-14(sd)
lin-4(lf) and lin-14(gf) have the same phenotype: they repeat S1.
LIN-4S is complementary to sequences in the 3’UTR of lin14.
Human miRNA genes
