b.They consist of four rings of seven polypeptide subunits that exist in alternative forms.
c.They are produced in response to IFN- produced during innate immune responses.
d.They produce a higher proportion of peptides containing acidic amino acids at the

Large pre-B cells undergo clonal expansion before the rearrangement of light-chain loci.
Which of the following are beneficial consequences of clonal expansion? (Select all that
apply.)
a.Autoreactive B cells are eliminated before the expenditure of energy needed to rearrange
a functional light-chain gene.
b.The energy used to make a functional heavy chain is not wasted as a result of the
inability to produce a functional light chain.
c.RAG gene expression is decreased, which in turn signals light-chain rearrangement.

a distinct light chain.
e.Approximately 85% of small pre-B cells will progress to the immature B-cell stage.
