1. This paper is about RNA can inhibit gene expression
RNA can destabilize mRNA
Single stranded RNA can affect gene expression
Double stranded RNA can affect gene expression
All of above.

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

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

4. From this study, we learn that RNA interference can be used to
inhibit expression of all C. elegans genes
Inhibit gene expression in other organisms
Inhibit gene expression in the next generation in C. elegans
Completely eliminate the expression of a C. elegans gene
None of above

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