The differences between results of Hershey and Chase’s original experiment and in new experiment in which 35 S (radioactive isotope of sulfur) labeled both protein and DNA, whereas 32 P (radioactive isotope of phosphorous) labeled only DNA. Introduction: Living beings transfer characters from one generation to another and the molecule responsible for transferring these characters is called genetic material. In the first half of the 20th century, scientists wondered which molecule of cell contains the genetic material; different scientists performed different experiments to find it. Hershey and Chase’s experiment gave evidence that DNA is the genetic material, after the experiments of Griffith (a substance transformed the bacteria pneumonia genetically), and the experiments of Avery and his coworkers (DNA is the genetic material that transformed nonvirulent bacteria to virulent bacteria).

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.

Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
