Your patient was cut by a rusty nail. You vaccinate her for tetanus. How does one of her B cells produce antibodies against C. tetani?
A. Each antigen is coded for by a unique
gene in the human genome; the correct gene
is activated to produce the antigens against
C. tetani.
B. Recombination of different gene segments
in B cells after exposure to C. tetani creates a
unique structural gene. The cell then
produces lots of that specific antibody.
C. Post-translational modification of a generic
antibody protein changes it from a generic
form to the correct specialized form against
C. tetani.
D. Recombination of different gene segments
in maturing B cells creates a unique structural
gene. Upon exposure to C. tetani, the cell is
stimulated to produce lots of the specific
antibody expressed by that gene.
