Question

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

(a) immunoglobulin

(b)interferons

(c) antitoxins

(d) lipoproteins

Answer 1

Correct option (b)interferons

Explanation:

Interferons (INFs) are a group of three vertebrate glycoproteins (α, β, γ ) (out of these, two (α and β) are produced within virally infected cells. Interferon act as antiviral protein by inducing synthesis of the enzymes which inhibit the viral production cycle. So, interferons are inhibitors of virus particles.
