.... basically a stable little (27-30 kD) green light bulb that can be tacked on to other proteins at either the N- or C-terminus without a distortion of its compact beta-can structure. Biochemists now frequently exploit GFP’s unique structural and physical characteristics to visualize various cellular activities. One such application of GFP is to understand the role of a hormone, T3, in the translocation of thyroid hormone nuclear receptors (TRs).* In this project, GFP was fused to the human TR subtype b1 protein and the protein’s intracellular movement was visually tracked in .....

.... five years. This double standard may have resulted from the wishes of those in power. Alcohol prohibition struck directly at tens of millions of Americans of all ages, including many of societies most powerful members. Marijuana prohibition threatened far fewer Americans, and they had relatively little influence in the districts of power. Only the prohibition of marijuana, which some sixty million Americans have violated since 1965 has come close to approximating the prohibition experience, but marijuana smokers consist mostly of young and relatively powerless Americans (Amer .....

.... speciation is the differences between the common giraffe (Giraffa camelopardalis), and the reticulated giraffe (Giraffa cameloparadalis reticula). These two subspecies have formed on different sides of the Tana River in Kenya. They are phenotypically distinct, and can only produce fertile offspring in zoos. Sympatric speciation occurs when two segments of the same species occupy a geographical area without interbreeding. Each new species, or subspecies, adapt to a specific environmental niche (adaptive radiation). Two segments of the same species Adapted to differ .....

.... weapons possible. In a fusion nuclear device such as a hydrogen bomb, lightweight nuclei are forced to fuse at very high temperatures into heavier nuclei, releasing energy and a neutron. In order to squeeze the two nuclei together, an atomic fission bomb is usually used. A fusion reaction releases about four times more energy per unit mass than a fission reaction. The United States supervised the development of the atomic bomb under the code name Manhattan Project, during World War II. The first nuclear chain reaction occurred in December 1942, at the University of Chicago. .....

.... declared that nuclear powers were safe and efficient. The truth is that accidents do happen at nuclear power plants and at other facilities all the time. An accident at a nuclear power plant has the potential to be much more harmful than an accident at a coal or gas plant because of the radiation that could be released. An example of this is Three Mile Island in Pennsylvania where there was a partial core meltdown in march of 1979 caused large amounts of radiation to be released into the atmosphere. Accidents involving US nuclear power plants are very rare. This does not m .....

.... if one waits too long to take car of their situation. Once a pimple in noticed, don't squeeze or scratch at it. This will help illuminate the spread of more pimples and scarring. Your hands carry many bacteria that will help to spread infection. This is not a good thing to do (Facts 2). When using cosmetics it is best to stay away from nonwater-based products and products that are rich in oils. These cosmetics will block the pores and trap the oils deep inside the skin, causing pimples. When washing your face be gentle. Do not wash with a dry soap or a soap high with pH .....

.... trace element fluoride found in water to provide for the proper protection of teeth. Fluoridation has been widely utilized in this country since 1945. It does not involve adding anything to the water that is not already there, since virtually all sources of drinking water in the United States contain some fluoride. Fluoridation is a form of nutritional supplementation that is not unlike the addition of vitamins to milk, breads and fruit drinks; iodine to table salt; and both vitamins and minerals to breakfast cereals, grains and pastas. The protection of fluoridation reaches c .....

.... of niacin, and 18 mg of iron. Nutritionists of today simplify this into an equation of 40% carbohydrates, 30% fats, and 30% protein that the entire day’s meals should be divided into. The total calorie intake must increase for active persons from 2200 to 2200 plus the total number used while exercising. This will ensure replenishment of the body’s system. With the wide variety of athletic competitions, the specific meal a competitor may need to eat to benefit themselves differs widely, as do the events. The last meal or two are extremely important in both thei .....
