answer A through D please! will thumbs up! :) Candace wants to become a veterinarian and is now studying at Harvard. She loves immunology and studies it at school. Candace has joined Harvard's research group studying the immunoglobulin genes in unicorns to see if they have similar organization and rearrangements to those in horses. To conduct their research, Candace obtained some hematopoietic stem cells from the mythical unicorn, Sunshine, and sequences them. Sunshine's DNA sequences were compared to another genome sequence of pegasus, which is a similar mythical horse, and she finds a heavy chain locus and two unique light chain gene loci. Candance names these dusk and dawn. The unicorn heavy chain locus is the following, with the general order of gene segments and RSS's shown. **(12 bp RSS black, 23 bp RSS gray) In the table below, the number of each different type of gene segment, identified by Candace, for the unicorn heavy chain as well as the dusk and dawn light chains are shown in the table below. A. How many possible heavy chain rearrangements can a unicorn like Sunshine make, due to the number of gene segments present in Sunshine's genome? B. How many possible dusk light chain rearrangements can unicorns make? C. How many possible dawn light chain rearrangements can unicorns make? D. How many antibodies of different antigen-binding specificities can a unicorn make due to the number of gene segments present in its genome?.
