not the brightest of them all

after having done the online bio quiz my school set, i conclude that the teachers are 1) over-ambitious 2) bored which leads to them having 3) too much time to watch grey's anatomy and 4) repressed humor to express.
15) By inserting foreign DNA containing a �healthy� gene into the nuclei of cells in diseased tissue during gene therapy, medical scientists hope to
A. get the foreign gene to make the product missing or mutated in the diseased tissue.
B. inhibit expression of about half of the genome of the diseased tissue.
C. turn on expression of many genes on the chromosomes of the diseased tissue
D. create weird, mutant animals
oooh har-har im sure the answer is D.
18) A three-year-old girl is scheduled for a tonsillectomy. As she is prepared for the operating room, her father becomes agitated and insists on accompanying her. He says that 2 of his 6 siblings have died during operations, one having a �reaction� to the anesthetic, the other never waking up. Which of the following options is the best response to the father�s anxiety?
A. Postpone the operation until the psychiatric state of the father can be evaluated.
B. Proceed after explaining that problems in father�s siblings are unlikely to be transmitted to his daughter.
C. Proceed after reassuring the father that drug reactions are environmental and unlikely to have a genetic basis.
D. Postpone the operation until a more detailed family history is obtained.
kind of LATE for the father to become agitated isnt it.
so the drama.
19) In the operating room, the child receives succinylcholine as a muscle relaxant to facilitate intubation and anesthesia. The operation proceeds until it is time for recovery, when the child will not begin breathing. A hurried discussion with the father discloses no additional problems in the family, but he does say that he and his wife are first cousins. The most likely possibility is
A. an autosomal dominant disorder that interferes with succinylcholine metabolism.
B. an autosomal recessive disorder that interferes with succinylcholine metabolism.
C. an X-linked disorder that that interferes with succinylcholine metabolism.
D. a lethal gene transmitted through consanguinity that affects the respiratory system
what they should do first is scream incest and lock the father away.
see what i said about too much grey's anatomy.
22) A karyotype was performed on an obese child and was entirely normal. Because his physician suspected a disorder known as Prader-Wili syndrome, Southern blotting was performed to determine the origin of the patient�s number 15 chromosomes. In part A of the figure below, a hypoethical Southern blot with DNA probe B15S8 defines which of the four restriction fragment length polymorphisms (RFLPs) are present in DNA from mother (M), child (C), and father (F). Based on the D15S8 locus, what is the origin of the child�s two number 15 chromosomes?
A. One from the mother, one from the father
B. Both from the father
C. Both from the mother
D. Results cannot be interpreted
this isnt so bad, until you read the next question.
23) Because part A of the figure demonstrates that the child is missing both paternal chromosome 15 alleles, nonpaternity would be a more plausible explanation than uniparental disomy.....
