C. elegans is a tiny, transparent nematode that is commonly used as a model organism in biological and genetics research. It is a widely studied organism due to its simple anatomy, short lifespan, and well-characterized genome. Researchers use C. elegans to study a wide range of biological processes, including development, aging, behavior, and disease. The organism's small size and rapid reproductive cycle make it particularly useful for genetic and molecular studies. Additionally, C. elegans is well-suited for high-throughput experiments, making it an ideal model for large-scale genetic and drug screening studies.
