Document Summary
B) you are studying an imaginary insect producing protein similar to immunoglobulins (ig) in humans. However, the difference is each ig molecule in this insect consists of one heavy chain and one light chain. Note- constant (c) segments of both heavy & light chains do not participate in somatic recombination. Ig (heavy chain): 50 v, 23 d and 7 j. Ig light chains: ig (kappa): 20 v and 5 j, ig (lambda): 40 v and 4 j. You find two strange bumps on your arm and decide to take some cells from each and examine them further. In the first bump, bump a, you find that the cells do not have contact inhibition, but they do have telomerase activity and they don"t have radiation induced cell death. In bump b, you find that there is no angiogenesis, normal cell death activity, and a normal life span. You have identified a new gene (congratulations!!) and named it red.
