Chapter 14, Problem 30P
The sequence at one end of one strand of the Drosophila transposon Mariner is shown below (dots indicate sequences within the transposon):
5′ TTAGTTTGGCAAATATCTCCCTTCCGCCTTTTTGATCTTATGT... 3′
You obtain a mutant bacterial strain tagged with an engineered Mariner transposon, cut the genomic DNA from this strain with the restriction enzyme MboI (whose recognition site is ^GATC), and circularize the resultant DNA fragments by diluting the restriction enzyme digest and adding DNA ligase.
| a. | Design two 17 bp PCR primers that you could use to identify (by inverse PCR) the gene into which the transposon inserted. |
| b. | What DNA sequence will be amplified from the circularized fragments of the mutant genome? Show the extent of this DNA sequence on a map of the genome of the mutant strain, indicating the locations of the transposon insertion and any relevant sites for the enzyme MboI. |

The Table blow gives the demand curve for doctor visits for Elena. If the price of a doctor's visit is $600, and Elena does not have health insurance, she will visit the doctor
times. If Elena obtains 50% coinsurance (the company pays 50% of the medical bill, Elena pays 50%), then Elena will visit the doctor times.

It alleged that when the mother was 13 years of age, the hospital negligently transfused her with Rh-positive blood. The mother's Rh-negative blood was incompatible with and sensitized by the Rh-positive blood. The mother discovered her condition 8 years later during a routine blood screening ordered by her healthcare provider in the course of prenatal care. The resulting sensitization of the mother's blood allegedly caused damage to the fetus, resulting in physical defects and premature birth.
