2. Lesch-Nyhan syndrome can be treated with gene therapy as it is caused by a malfunction in the enzyme HPRT. This syndrome can cause mental disability, cerebral palsy and uncontrollable urges to mutilate oneβs own body. Mickey, 12-year old boy who has this syndrome, is confined to a wheelchair and must be under constant supervision to make sure he does not hurt himself. His care has been difficult on his parents both financially and emotionally. Knowing that Mickey does not have much longer to live and that his current life is painful, his parents have called a doctor known for her success with gene therapy to ask for a consultation.
Outline the steps that would be involved in a treatment such as this. Select the BEST answer.
Select one:
a. Insert gene into vector β study disease β insert vector into patient
b. Study disease β insert vector into patient β insert gene into vector
c. Select vector β study disease β insert vector into patient
d. Select vector β insert gene into vector β insert vector into patient

b. A human treated with insulin produced by E. coli bacteria.
c. A sheep developed from an egg cell fertilized in the laboratory.
d. A sheep that produces a cow protein.
4. Which of the following is NOT a way that bacteria obtain new combinations of genes?
Select one:
a. Two bacteria join together and one passes a plasmid to the other.
b. Bacteria produce haploid gametes that undergo fertilization.
c. Bacteria absorb free pieces of DNA from their environment.
d. All of the above are true.
5. Which of the following factors does NOT increase the chance of a strain of bacteria becoming resistant?
Select one:
a. Taking antibiotics for problems other than bacterial infections.
b. Taking all of the antibiotic prescribed in the appropriate amount of time.

What kind of seafood would you expect to have the highest levels of mercury and why? kelp, because they use the sun to photosynthesize on the bottom trophic level. oysters, because they filter feed on plankton on a lower trophic level. small fish, because they eat plankton on a higher trophic level. sharks, because they feed on organisms on a higher trophic level.
