試題詳解

56. Sequencing an entire genome, such as that of Caenorhabditis elegans, a nematode, is most important because
(A) it allows researchers to use the sequence to build a "better" nematode, 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.
