Document Summary

Have at least 4 different molecules at one gene site: variations of genes called alleles. At the v1 there"s 50 alleles, at the diversity there is 25, at the joining site there are 6: total 75 000. Can make gamaglobuilin in 4 different flavors. Every time an immune response begins in humoral. Transcription to rna and in cytoplasm it makes it specific antibody. Need to switch mu for g antibody have gama now and it produces an igg. When an antibody response is complete, there is a large number of cells produce from that antigen: the cells that are now done with die via apoptosis programmed death. Need to remember that activity has occur: b cells, plasma cell, lymphocyte series is deposited in lymph nodes as memory cells, ready to save your life next time. Deposited in the apical light zone of the lymph node.
