The B lymphocytes produce an army of proteins in response to pathogens into our body to fight with them and T lymphocytes help B lymphocytes to produce that army.

And such proteins are known as

1.    Cytokines

2.    Interferons

3.   Antibodies

4.   Allergen

When plants/animals are infected with virus, they may produce an anti-viral substance that is capable of inhibiting the multiplication of that virus. Identify the correct name of this substance.
1. Virion
2. Antiviron
3. Antigen
4. Interferon

Interferons are secreted by:
1. Liver
2. Spleen
3. Virus infected cells
4. Lymphocytes

The type of immunity responsible for graft rejection by a recipient body is 
1. Innate immunity 
2. Humoral immunity 
3. Cell mediated immunity 
4. Either 2 or 3 

Anamnestic Response is generated by

1.    First interaction of the pathogen with the body

2.    Second interaction of the pathogen with the body

3.   Response against self cells

4.   Response against not a potential antigen

Interferon is a glycoprotein which is: 

1. Antibacterial

2. Antifungal

3. Antiviral

4. All of these

Maturation of lymphocytes takes place in

The secretion of antibodies by B lymphocytes provides:
1. Passive immunity 
2. Humoral immunity 
3. cell mediated immunity 
4. Innate immunity 

Antigen binding site in an antibody is found between 

1. two light chains

2. two heavy chains

3. one heavy and one light chain 

4. either between two light chains or between one heavy and one light chain depending

upon the nature of antigen.

Cells of immune system that do not provide innate immunity are

1. T-lymphocytes

2. Neutrophils

3. NK cells

4. Macrophages
