Answer 1

Answer

1) False

Explanation : Reovirus has dsRNA

2) True

Explanation : Interferons are proteins that can induce a nonspecific resistance to viral infection by several mechanisms, including the inhibition of protein synthesis, inactivation of viral RNA, and enhancement of phagocytic and cytotoxic mechanisms.
