an evolutionarily conserved mechanism that protects cells against invasive nucleic acids such as viruses, transposons and transgenes
an extraordinary phenomenon that has rather recently become a resource for studying a vast array of viral diseases in both the plant and animal kingdoms
a novel nucleic acid-based antiviral immunity in mammalian cells
a recently discovered defense mechanism against virus infection in plants and invertebrates
a type of natural immune defense in which sequence-specific RNA degradation follows the recognition of double-stranded RNA (dsRNA)
