A study is conducted on immune responses to antigens. It is shown that there are immune responses to every type of infectious agent encountered throughout the life span. These immune responses include both $T$ and $B$ cells capable of responding to infections. Through which of the following mechanisms is this diversity of response most likely to be developed?

Group of answer choices

Encounters with infectious agents

Random recombination of some genes

MHC class I and II genes inherited from parents

Selection in thymus and bone marrow

Accepted Answer

***B*** ∻Key Concept∻ ⚹Random recombination of some genes⚹ ∻Explanation∻ ⚹The diversity of immune responses is primarily developed through the random recombination of gene segments that encode the variable regions of T-cell receptors and B-cell receptors. This process generates a vast array of unique receptors capable of recognizing a wide variety of antigens.⚹◊What role do MHC class I and II genes play in the development of diversity in immune responses to antigens?⍭ Generate me a similar question◊
