Question

Assertion: Virus-infected cells secrete proteins known as interferons.
Reason: Interferons protect the non-infected cells from bacterial infection.

• A. Assertion is true but Reason is false.

• C. Both Assertion and Reason are false.
• D. Both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.

Answer 1

The correct option is A Assertion is true but Reason is false.

Virus-infected cells secrete proteins called interferons which protect non-infected cells from further viral infection. Interferons are a group of related low molecular weight regulatory cytokines produced by certain eukaryotic cells in response to a viral infection. Besides defending against viruses, they also help to regulate the immune response.
