Chapter 9, Problem 8P
The linear bacteriophage λ genomic DNA has at each end a single-strand extension of 20 bases. (These are sticky ends but are not, in this case, produced by restriction enzyme digestion.) These sticky ends can be ligated to form a circular piece of λ DNA. In a series of separate tubes, either the linear or circular forms of the DNA are digested to completion with EcoRI, BamHI, or a mixture of the two enzymes. The results are shown here.
| a. | Which of a. the samples (A or B) represents the circular form of the DNA molecule? How do you know? |
| b. | What is the total length of the linear form of the λ DNA molecule? |
| c. | What is the total length of the circular form of the λ DNA molecule? |
| d. | Draw diagrams of the circular and linear λ DNA molecules, showing the locations of the EcoRI and BamHI sites. |

A negligence action was brought by a mother against a hospital on behalf of her minor daughter. 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.
Did a patient relationship with the transfusing hospital exist?
