Question

Small proteins produced by vertebrate cells naturally in response to viral infections and which inhibit multiplication of viruses are called

(a) immunolobulins

(b) interferons

(c) antitoxins

(d) lipoproteins

Answer 1

The correct option is (b) interferons.

Explanation:

Interferon (INFs) are a group of three vertebrate glycoproteins (α, β, γ) Out of these, two (α and β) are produced within viral infected cells. Interferon induces, among adjacent cells, as antiviral state by inducing synthesis of the enzymes which inhibit the viral production cycle. Thus, inhibiting multiplication of virus in the body.
