... additional factors may also play some role in the generation of WNV diversity in these, or other replicating lineages. Previous studies attempting to detect recombination in West Nile virus used ... was maintained to allow confirmation of the recombination event by examining the similarity existing between the minor parent and recombinant sequences represented by differences in...

Results: ... appear to actively inhibit the RNAi response, but rather avoided degradation by replicating in a manner that was inaccessible to the RNAi machinery. Results In vitro generated siR...
