Sequencing an entire genome, such as that of C. elegans, a nematode, is most important because
A) it allows researchers to use the sequence to build a "better" nematode, which is resistant to disease. B) it allows research on a group of organisms we do not usually care much about. C) the nematode is a good animal model for trying out cures for viral illness. D) a sequence that is found to have a particular function in the nematode is likely to have a closely related function in vertebrates. E) a sequence that is found to have no introns in the nematode genome is likely to have acquired the introns from higher organisms.
