Textbook Question
Chapter 1, Problem 3P
The size of one copy of the human genome is approximately 3 billion base pairs, and it contains about 25,000 genes organized into 23 chromosomes.
| a. | Human chromosomes vary in size. What would you predict is the size of the average chromosome? |
| b. | Assuming that genes are spread evenly among chromosomes, how many genes does an average human chromosome contain? |
| c. | About half of the DNA in chromosome contains genes. How large (in base pairs) is an average human gene? |

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?
