abstract：:Interferon induces the synthesis of an enzyme which synthesizes 2',5'-oligoadenylate [2',5'-oligo(A)] when activated by double-stranded RNA. The 2',5'-oligo(A) in turn activates an endonuclease (RNase L). Concentrations of 2',5'-oligo(A) sufficient to activate RNase L are formed in interferon-treated HeLa cells infect...
