Rather, we found that most transcripts that form dsRNA structure simply have more dsRNA structure/stability in the absence of TDP-1 (examples of enriched antisense-overlap genes shown in Supplementary Fig S11A).
The absence of, for example, the outward K+ channel Tok, may be harmless if the organism is not exposed to severe hypoosmotic shocks and the subsequent need to quickly release the surplus K+.
