Do HOX genes play a role in the development of C. elegans?

#SCPH01 Biochemistry
  1. No, C. elegans does not have HOX genes
  2. No, C. elegans has HOX genes but none of them are used during development
  3. Yes, C. elegans has 4 clusters of HOX genes, just like mammals, that are required for specification of the identity of structures during embryogenesis
  4. Yes, but only one HOX gene is required in the embryo; the others provide positional identity in the larva
