(A)  Janeway’s figure to the left illustrates features of immunoglobulin light (IgL) chains.  Considering features of the immunoglobulin heavy (IgH) chain, where is the variability encoded for the HV1 (CDR1), or how is the variability generated somatically?  (2 points) (B)  Considering features of the IgH chain, where is the variability encoded for HV3 (CDR3), or how is the variability generated somatically?  (2 points) (C)  Where in the genome is framework region 4 (FR4) encoded for IgH chains?  (2 points) (D)  Briefly explain why a VH segment cannot join directly with a JH segment.  (2 points) (E)  Briefly describe one advantage and one disadvantage of junctional diversity during the rearrangement of immunoglobulin gene segments.  (2 points)
