The T cell receptor repertoire is greater than that of the B cell repertoire of unique receptors for all of the following reasons EXCEPT:
|
a greater number of diversity segments that can be joined |
||
|
a greater number of joining segments that can be joined |
||
|
a greater number of V segments that can be recombined |
||
|
greater junctional diversity |
Which of the following is incorrectly matched with its function in the T cell receptor complex?
|
Zeta ; signal transduction upon TCR activation |
||
|
alpha and beta constant regions ; isotype switching after activation |
||
|
TCR alpha and beta chain variable regions ; antigen binding |
||
|
CD3 ; transport of TCR from ER to cell surface and stabilization of TCR |
An individual who is ___________ at their HLA loci has a more robust immune response in a given environment than an individual who is ___________.
An HLA-_________ individual has a fully functioning immune response, but is limited in the range of antigens that can be bound by their HLA molecules.

Homework Answers
1. D diversity is due to VDJ recombinations
2. B alpha and beta is not related with T cells
3. C heterozygous HLA have certain immune problems and conditions like rheumatic arthritis.
