Diabetes is a disease caused by a change in the amino acid sequence of the insulin protein. Suppose
the target DNA sequence in the normal insulin gene is GAC. Bob the Builder has a mutation that
causes his DNA sequence to read TAC instead. Will Bob be diabetic? If so, why? If not, why not?
Explain fully using appropriate vocabulary. You will need to transcribe and translate each DNA
sequence to receive full credit, and explain why this would or would not cause a disease.

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(μm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
