Is it true that biological systems possess intrinsic antiviral defense mechanisms such as RNA interference?
Yes. Multiple studies and reviews demonstrate that biological systems across a wide range of eukaryotes utilize RNA interference as an intrinsic antiviral defense mechanism.
Verdict: SUPPORTED · 9 sources for, 0 against · Last checked
The analysis
The retrieved papers consistently support the claim that biological systems (such as plants, invertebrates, and other eukaryotes) use RNA interference (RNAi) as an intrinsic antiviral defense mechanism. The evidence is robust and unanimous across the provided literature.
