If a B cell clone began to produce antibody
with altered binding strength and specificity for antigen, you
would expect the mutation of the antibody gene to involve:
A. |
The variable region of the heavy chain
or the constant region of the light chain |
B. |
The variable region of the light chain
or the constant region of the heavy chain |
C. |
The variable regions of the light or heavy
chains
The variable coding regions of both
light and heavy chains determine antigen specificity.
|
D. |
The constant regions of the light or heavy
chains |
