A. This diversity is generated from 108 different immunoglobin genes. B. Most of these antibodies recognize self-antigens. C. Most of these antibodies recognize proteins.  D. Most of these antibodies recognize small organic molecules. E. There are really just a small number of antibodies, each of which can bind to many different antigens. The antibiotic penicillin is a small molecule that does not induce antibody formation. However, penicillin binds to serum proteins and forms a complex that in some people induces antibody formation resulting in an allergic reaction. Penicillin is therefore A. an antigen B. a hapten C. an immunogen D. both an antigen and a hapten

13. Which of the following types of interactions result in proteins folding so that nonpolar residues are on the interior of the protein, protected from water? a. hydrogen bonds b. salt bridges c. disulfide bonds d. hydrophilic interactions e. dispersion forces

10. Enzymes that have binding sites for modulators are specifically called a. zymogens Ob. quaternary proteins c. induced enzymes d. allosteric enzymes

4. Analyzing: A. Analyze the pedigree below and determine if the trait is inherited as autosomal dominant, autosomal recessive, X-linked dominant, X-linked recessive, or Y-linked. Remember, data from human families is limited, so you may be unable to determine the inheritance with certainty. The key is that you justify your answer using data from the pedigree. 5 2 7 11 14 8 12 15 3 13 4 10 B. Two family members (individual four and individual 12) decide to undergo genetic counseling and testing for the disease. • Genetic testing shows that individual 4 has only nonmutant allele(s) • Genetic testing also indicates that individual 12 has only mutant allele(s) Does this information change your assessment of the inheritance of the disease? If so, explain why; if not, explain why not.

Which statement(s) is(are) true about carbonic anhydrase enzyme?A. Carbonic anhydrase enzyme controls the production of carbonic acid.B. Carbonic anhydrase enzyme controls the pH of human blood.C. Zn metal is present in the catalytic site.
