Accepted Answer

Somatic hypermutation

Answer

Antigen presentation

Answer

Clonal selection

Answer

Phagocytosis

Question 2

What role does V(D)J recombination play in antibody diversity?

Accepted Answer

It generates unique variable regions for antibodies.

Answer

It destroys non-functional B cells.

Answer

It produces memory T cells.

Answer

It enhances the affinity of existing antibodies.

Question 3

Accepted Answer

Class switching

Answer

Affinity maturation

Answer

Neutralization

Answer

Opsonization

Question 4

Accepted Answer

Combination of V, D, and J gene segments

Answer

Antigenic drift

Answer

Natural selection

Answer

Endosomal processing

Question 5

Which type of antibody is produced first in response to an antigen?

Accepted Answer

IgM

Answer

IgA

Answer

IgG

Answer

IgE

Question 6

Which of the following is NOT a mechanism by which antibodies promote pathogen clearance?

Accepted Answer

Cell division

Answer

Complement activation

Answer

Opsonization

Answer

Neutralization

Question 7

What is the significance of antibody affinity maturation during an immune response?

Accepted Answer

It increases the binding strength of antibodies to antigens.

Answer

It generates a faster immune response.

Answer

It ensures antibodies are rapidly destroyed.

Answer

It leads to the production of more antibody types.

Question 8
