Before their study, it is known that
A. Single stranded RNA can cause RNA interference
B. Sense RNA can cause RNA interference
C. Anti-sense RNA can cause RNA interference
D. RNA interference can persist into next generation
E. All of above

Potent RNA interference can be caused by
A. dsRNA corresponding to any sequence of its target
B. dsRNA corresponding to the coding region of its target
C. Anti-sense strand RNA corresponding to the exon of its target
D. Sense strand RNA corresponding to the intron of its target
E. None of above

From this study, we learn that RNA interference can be used to

B. Inhibit gene expression in other organisms
C. Inhibit gene expression in the next generation in C. elegans
D. Completely eliminate the expression of a C. elegans gene
E. None of above

This paper shows that RNA interference results in
A. Degradation of its target mRNA
B. Inhibited transcription of its target gene
C. A defect in RNA splicing
D. Altered chromatin structure of its target gene
E. None of the above
