A C. elegans with nuclei (DNA) labeled (DAPI stained). Each colored spot (light blue) represents a cell of the C. elegans.
This figure shows one wild type (in upper left corner) and 5 locomotion defect worms. As you can see, the moving patten of mutants is different from wild type. This is to show how locomotion defect can affect worms' motion.
