Sequencing an entire genome, such as that of C. elegans, a nematode, is most important because

#Unit 13. Methods in Biology
  1. it allows researchers to use the sequence to build a ʺbetterʺ nematode, resistant to disease.
  2. it allows research on a group of organisms we do not usually care much about.
  3. the nematode is a good animal model for trying out cures for viral illness.
  4. a sequence that is found to have a particular function in the nematode is likely to have a closely related function in vertebrates.
