Phenotypes of worms exposed to dsRNA hairpins. (A) Motility of wild-type (WT), pha-4::GFP, or pGFP transgenic worms after RNAi induced with GFP- unc-22 hairpin dsRNA (GFPhp). Three F1 animals were allowed to move freely for 11 min and photographed in the absence (no treat) or presence of GFP–unc-22 hairpin dsRNA. (B) GFP fluorescence for pha-4::GFP transgenic worms treated with no dsRNA (no treat), or GFP–unc-22 hairpin dsRNA (GFPhp).
