Question

Mark ALL appropriate answer(s). Each incorrect. choice earns -l/2 point. Generation of diversity by genetic rearrangements applies only to B cells applies only to T cells applies equally to both B cells applies to both B cells, but differently: far more junctional site diversity in B cells compared to T cells applies to both B cells, but differently: far more junctional site diversity in T cells compared to B cells is less critical in B cells than because B cell function depends on T cells is less critical in T cells than B cells because T cells must undergo 'thymic education' simply cannot exist You immunize a rabbit with DNP-BSA in order to make anti-DNP IgG. While giving a booster shot 3 weeks later, you spill your DNP-BSA as the rabbit kicks you. The chemist who makes the DNP conjugates is on vacation, but you do have some DNP-OVA. In order to induce a secondary immune response to DNP, your ONE BEST option is a. administer anti-DNP ab (passive transfer of immunity) prior to challenge with DNP-OVA. boost with DNP every week. immunize with OVA and wait 11/2 weeks before sensitization with DNP-OVA start all over: immunize with DNP-OVA and wait 3 weeks before boosting with DNP-OVA use passive transfer of anti-OVA ab as you challenge with DNP-OVA. inject PBL (peripheral blood lymphocytes) from a syngeneic rabbit sensitized with OVA (you happen to have this ready, fortunately) (adoptive transfer of immunity) at the same time that you inject DNP-OVA 1 week before injecting DNP-OVA, transfer CD8 T cells from a syngeneic rabbit sensitized with OVA none of the above; give up. None of this will work because of the carrier effect; you have to stick to DNP-BSA. In the above immunization,
