Anamnestic Response is generated by

  •     First interaction of the pathogen with the body

  •     Second interaction of the pathogen with the body

  •    Response against self cells

  •    Response against not a potential antigen

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

  •     Cytokines

  •     Interferons

  •    Antibodies

  •    Allergen

The response generated by antibodies is called

  •     Cell-mediated Immune response

  •     Humoral immune response

  •    Primary immune response

  •    Anamnestic immune response

During transplantation, which immunity causes rejection?

  •     Humoral immunity

  •     CMI

  •    Innate immunity

  •    Antibody mediated immunity

In the structure of an antibody; which terminal has antigen-binding site?

  •     N

  •     C

  •    N terminal of heavy chain and C terminal of light chain

  •    C terminal of heavy chain and N terminal of light chain

IgM is pentamerous and the weight of the heavy chain is 1000000 Da and that of the light chain is approximately half of the heavy chain, then find the weight of IgM.

  •     More than 1500kDa

  •     150kDa

  •    15 kDa

  •    300 kDa

If IgM is pentamerous and the weight of antibody is around 1500000 Da. It is provided that the weight of the heavy chain of the antibody is twice that of the light chain. Then find the approximate weight of dimeric antibody IgA.

  •     More than 590kDa

  •     550kDa

  •    300kDa

  •    30kDa

If person X contracts a disease successfully, which kind of immunity has he developed?

  •     Active

  • 2    Passive

  •    Anamnestic

  •    Humoral

Colostrum and immunity gained through the placenta come under which class of immunity?

  •     Natural

  •     Passive

  •    Active

  •    More than one option

When a quick immune response is required, we administer which kind of immunization?

  •     Active

  •     Passive

  •    Both depending on the pathogen

  •    Generally active sometimes passive

RDT has not allowed producing an antigenic polypeptide of the pathogen in

  •     Bacteria

  • .    Yeast

  •     Virus 

  •    Both 1 and 2

The cause of autoimmunity can be

  •     Physical appearance

  •     Genetic reasons

  •    Reasons, which are still under research

  •    Both 2 and 3

The primary lymphoid organs are

  •     Bone marrow and thymus

  •     Bone marrow and spleen

  •    Spleen and thymus

  •    All three

Which of the following is not a lymphoid organ?

  •     Appendix

  •     Thyroid

  •    Peyer's patches

  •    Tonsils

The formation of effector lymphocytes will occur in

  •     Bone marrow

  •     Thymus

  •    Appendix

  •    Thyroid

What is the main lymphoid organ where all blood cells including lymphocytes are produced?

  •     Spleen

  •     Thymus

  •    Lymph nodes

  •    Bone marrow

The microenvironment  for the maturation and development of T lymphocytes is created by

  •     Bone marrow

  •     Thymus

  •    Both A and B

  •    Spleen

The immature lymphocytes differentiate into antigen sensitive lymphocytes in

  •     Bone marrow

  •     Thymus

  •    Both A and B

  •    Spleen

The site of interaction of lymphocyte with antigen is

  •     Bone Marrow
