Question

_____ 12) All of the following statements about interferon are true, EXCEPT A) synthesis of interferon is induced by viral double-stranded RNA B) Interferon induces synthesis of enzymes that inhibit protein synthesis C) interferon prevents the viruses from fusing and entering neighboring cells D) interferon can be produced by fibroblasts and T-cells

Answer 1

A) synthesis of interferon is induced by viral double-stranded RNA ----> TRUE

B) Interferon induces synthesis of enzymes that inhibit protein synthesis ----> TRUE

C) interferon prevents the viruses from fusing and entering neighboring cells ----> TRUE

D) interferon can be produced by fibroblasts and T-cells ----> FALSE

Interferons (IFNs) are the proteins (chemical messengers) released by cells (lymphocytes, macrophages, other cells infected with viruses etc.) in response to pathogenic organisms such as viruses, tumour cells, bacteria etc. Phagocytes detect the presence of pathogens than before INFs do.
