50. Which one is the best gene expression explanation of why the human immune system could respond to different types of pathogens (i.e., the receptor diversity)?
(A)This is because there are a lot of introns in the human evolutionary history that recoded the types of pathogen genetic information.
(B) This is because there are a lot of exons in the human evolutionary history that recoded the types of pathogen genetic information.
(C) This is because there are many types of V segments and J segments in the Ig genes that could assemble into the antigen receptors to respond to the pathogen.
(D)This is because there are many types of C segments and J segments in the Ig genes that could assemble into the antigen receptors to respond to the pathogen.
(E)This is because there are many types of V segments and C segments in the Ig genes that could assemble into the antigen receptors to respond to the pathogen.
