Why is c elegans a good model organism
The reasons listed by Nautica are probably the only reason why these organisms are used but I would add that C. elegans, E. coliand other model organisms are just use because there were easily accessible 50 years ago and many people did reasearches on them but many of them are crappy models. These models are good for the general knowledge but ...Why is C. elegans a good model organism? - rapid generation time - DNA can be added via microinjection - can reduce gene function via RNAi (RNA interference) : knock down levels of expression of genes - life cycle of 4 days - helpful to understand development - see which cells give rise to other cells.
