Why is c elegans a good model organism
Caenorhabditis elegans is now the model organism of choice for a growing number of researchers. A combination of its apparent simplicity, exquisite genetics, the existence of a full molecular toolkit and a complete genome sequence makes it ideal for rapid and effective study of gene function.To do so, he’s getting big help from a little worm, the nematode Caenorhabditis elegans. Transparent, C. elegans reaches only about 1 mm in length and doesn’t have a heart or circulatory system. Nine hundred and fifty-nine cells make up its entire body, and it’s this simplicity that makes it a valuable model.
