Which of the following statements is incorrect concerning antigen-specific receptors on both B and T cells?
A) They are clonally distributed transmembrane molecules.
B) They have extensive cytoplasmic domains that interact with intracellular molecules.
C) They consist of polypeptides with variable and constant regions.
D) They are associated with signal transduction molecules at the cell surface.
E) They can interact with peptides derived from nonself antigens.

B the most probable...
but one doubt....antigen specific receptors are surface or transmembrane molecules????
help...

Probably B
drduck, I think antigen specific receptors are transmembrane molecules .

B
Both the TCR and Ig have short cytoplasmic tails. The signal transduction molecules associated with the antigen-binding chains interact with intracellular molecules.

Yes .. and I would like to add that ... Both the surface receptors .. (Ig M D and TCR) ... span Transmembrane ... !! Sooo .. Didnt know that before .. !!
