Mаndаtоry Questiоn: Everyоne MUST аnswer this question (14 pts total). Question 1: The total number of immunoglobulin genes in humans are at 2.5 x 105, whereas the total repertoire of immunoglobulin diversity is estimated at 5 x 1013. How can there be so many Ig variants? 1a. “7 Pts” One of the key features of immunoglobulin and TCR genes is that there are multiple genes present in the genome. The accompanying Table lists a hypothetical number of variable, diversity and joining genes in humans for the heavy and c light chains. From this table, calculate heavy chain diversity, light chain diversity and total diversity. 1b. “ 7Pts” Is existence of multiple genes enough to explain all Ig diversity found in B cells. What mechanisms are in place create such diversity. What is the major mechanism of creating such diversity?
