Summary Introduction

To explain:

Mutations that promote cancer have different effects on the proteins encoded by proto-oncogenes and tumor suppressor genes.

Introduction:

Mutation is a sudden and heritable change in the DNA (deoxyribonucleic acid) of an organism. Mutations in certain genes often result in cancer. Cancer is a disease characterized by the uncontrolled division of cells. Cancer cells have distinct features than normal cells. The cytoplasm is reduced, multiple nuclei are present, chromatin is coarse, and nucleoli are also multiple and enlarged in cancerous cells.

What are biofertilizers and mention the significance
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?
