Why are c elegans good model organisms.

Model organisms are species that are highly studied by scientists, meaning they are well known and their biology is understood in depth. For example, C. elegans (a microscopic worm) is so well understood that scientists know the order in which each cell will grow throughout its lifetime. Model organisms are often chosen in research because they ...C. elegans is a powerful model system for exploring the molecular mechanisms of early development as well, for several reasons: (1) Genetics: Mutants can be isolated that have specific defects in development, and the mutated gene can be identified through positional cloning. (2) Genomics/Proteomics: C. elegans was the first higher eukaryote ...The evolution of these sensory modalities confers numerous benefits to survival, including the ability to find food and mates and to avoid hazard. Figure 1 –. The primary sensory modalities in Caenorhabditis elegans. Worms possess a rich repertoire of sensory modalities, sensing mechanical forces, chemicals, light, and temperature. Introduction. The eukaryotic multicellular organism Caenorhabditis elegans which has completely sequenced genetic profile, is an established genetic model organism (), that can be used to study aging.The use of C. elegans as a model system to recapitulate most human diseases in recent decades is invaluable for experimental research at both the metabolic and genomic levels in vivo (2, 3).
