B) adhesion and opsonization
C) transcription and margination
D) replication and translation
E) proliferation and division

Question

Quizplus · Accepted Answer

Proliferation and division are the processes by which a lymphocyte undergoes clonal selection in response to an antigen. Once a lymphocyte recognizes an antigen, it proliferates and divides to form multiple clones of identical cells, each with the ability to recognize and respond to that antigen. This amplifies the immune response and allows for targeted elimination of the pathogen carrying the antigen. Chemotaxis and diapedesis refer to the movement of immune cells towards a site of infection; adhesion and opsonization are processes by which immune cells bind to pathogens; transcription and margination are not directly related to lymphocyte activation. Replication and translation are general biological processes that do not specifically relate to the activation of lymphocytes.
