To introduce dsRNA into C. elegans, it is enough just to dip the worms into media that includes E. coli containing the dsRNA because ________.
◦ E. coli infect C. elegans and then the RNA is released
◦ E. coli DNA integrates into the genome of C. elegans
◦ C. elegans feed on the transgenic bacteria
◦ C. elegans emit toxins that paralyze the bacteria
◦ E. coli emit chemicals that cause pores to open in the nematode body wall
