Which statements are true? Explain why or why not.1 T cells whose receptors strongly bind a self-pep-tide–MHC complex are killed off in peripheral lymphoidorgans when they encounter the self peptide on an anti-gen-presenting dendritic cell. 2 To guarantee that the antigen-presenting cells inthe thymus will display a complete repertoire of self pep-tides to allow elimination of self-reactive T cells, the thy-mus recruits dendritic cells from all over the body. 3 The antibody diversity created by the combinato-rial joining of V, D, and J segments by V(D)J recombinationpales in comparison to the enormous diversity created bythe random gain and loss of nucleotides at V, D, and J join-ing sites.
Describe the typical shape and structure of an antibody. Distinguish between antibodies and antigens. Be able to draw an antibody and label the variable (antigen-binding) region and the control region.
