Question

Match the following.

List I	List II
(A) Interferon	(I) $F_{ab}$
(B) Paratope	(II) Inflammatory mediators
(C) Interleukins	(III) Antiviral proteins
(D) Histamine	(IV) White blood cells
	(V) Anticoagulant

• A. A- III B-I C-II D-IV
• B. A- III B-I C-IV D-II
• C. A- III B-IV C-V D-II
• D. A- III B-II C-IV D-V

Answer 1

The correct option is B A- III B-I C-IV D-II

• Interferons are the proteins which are released by the virus-infected cell which induces antiviral mechanism in the neighbouring cells.
• Paratope is the region present at the end of the variable region of the F${}_{ab}$ fragment. It is the exact site where the antigen binds.
• Interleukin is a type of cytokine signaling molecule in the immune system. It is a protein that regulates the activities of white blood cells.
• Histamine is a nitrogenous compound which is involved in the inflammatory response as well as it acts as a neurotransmitter.

Thus, the correct answer is option B.
