Textbook Question
Chapter 12, Problem 12PDQ
Mammals contain a diploid genome consisting of at least 109 bp. If this amount of DNA is present as chromatin fibers, where each group of 200 bp of DNA is combined with 9 histones into a nucleo-some and each group of 6 nucleosomes is combined into a solenoid, achieving a final packing ratio of 50, determine (a) the total number of nucleosomes in all fibers, (b) the total number of histone molecules combined with DNA in the diploid genome, and (c) the combined length of all fibers.

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?
