It has become one of the "model" organisms in biology. It is a true animal with at least rudiments of the physiological systems - feeding, nervous, muscle, reproductive - found in "higher" animals like mice and humans.In this video, we reviewed the characteristics of C. elegans and the reasons that make worms a powerful model organism. This tiny worm, with its simple genetics and diminutive nervous system, has helped us to understand numerous aspects of human development, behavior, aging and disease. Thanks for watching, and good luck with your C. elegans ...
