Document Summary

Apoptosis is the process by which old or defective cells are removed from the body to prevent tumor cell growth. T cells and b cells both have receptors for foreign proteins. T cell receptors are found in the membrane. B cell receptor proteins are found in bodily fluids and are called antibodies. Pasteur"s gooseneck flasks and the meat/maggot experiment were used to disprove spontaneous generation, and the germ theory of disease. In burkitt"s lymphoma, translocations cause chromosomes to break and stick together. This leads to myc gene activation and b cell proliferation (hyperplasia) Cancer is an umbrella term that refers to over 200 diseases who share abnormal, uncontrolled cell growth, and the ability to metastasize and damage tissue. Maps of africa show the incidence of malaria and burkitt"s lymphoma (bl) largely overlap. This observation suggests malaria is a risk factor for bl. In humans, cancer can be caused by viral infection, gene mutation, and environmental exposure.
