Late 19 Th Century Law Of Nature
1,664 wordsWhy is AIDS so difficult to cure? How does the AIDS virus attack the body? In 1979, the first reported AIDS case occurred in New York, and by mid-June 1981, unusual immune system failure among gay men was surfacing in the United States. The Centers for Disease Control (CDC) initially name the disease GRID, or gay-related immune deficiency, because it was prominently found among homosexuals. It appeared to be a lifestyle-associated illness, linked to excessive stress to the immune system. Researc...

Rate Of Reaction Hydrogen Bonding
2,165 wordsRESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

Year Old Girl Fruits And Vegetables
1,173 wordsDr. Bernard D. Davis, professor of bacterial physiology at Harvard medical school in Cambridge, stated that after twenty years of expanding experience with biotechnology with no detectable harm to humans or to the environment, this concern has turned into a good idea (q. In Bender and Leon 23). Genetic engineering is defined as the scientific alteration of the structure of genetic material in living organisms. Although under heavy scrutiny, genetic engineering will someday be used to cure geneti...

Studies Have Shown Blood Vessels
1,197 wordsBiological regeneration has been studied over the years, in salamanders, and biological imitations of life. Through research on the mitotic capabilities of certain animals, to the DNA and hormones that make regeneration possible, scientists are slowly finding a way so that humans can regenerate lost or missing limbs, or grow organs used to save millions of lives in the future. Because being able to reproduce a limb or body part is dependent on nerves, scientists have found it vital to perform es...

Factor Viii Clotting Factor
878 wordsAccording to the dictionary Hemophilia is a hereditary disorder in which the blood fails to clot normally, causing prolonged bleeding from even minor injuries. This is only the very basis of this disorder. First of all there are two kinds of Hemophilia. Hemophilia A and Hemophilia B. Hemophilia A is caused by lack of protein factor VIII and is found in 80 % of hemophiliacs. Other names for this are classical hemophilia, factor VIII deficiency hemophilia. Hemophilia B is caused by a deficiency of...

Insulin Dependent Diabetes Mellitus Type Ii Diabetes
1,389 wordsNon Insulin dependent diabetes mellitus is the name given to a disturbed chemical balance in the body, which can affect a number of different organs. The word diabetes comes from a Greek expression meaning, siphon. (Nova) It refers to the increased urination and thirst that occurs in newly diagnosed cases. These symptoms are due to the high sugar (glucose) content in the urine. The sugar drags water out with it, the body gets dry and you feel thirsty. All this follows an excessive build-up of gl...

Permeable Membrane Semi Permeable
781 wordsOsmosis is the flow of water through a semi permeable membrane that blocks the transport of salts or other solutes through it. It is also defined as the net movement of water from an area of high concentration to a region of low concentration. Osmosis is a fundamental effect in all biological systems. When two water volumes are separated by a semi permeable membrane water will flow from the side of low solute concentration to the side of high solute concentration. If external pressure is applied...

Infertile Couples Genetic Defects
1,159 wordsThe rapid development of the technology for cloning has led to moral debates around the world on whether or not to ban creating human clones. With the advancement of clone technology two states, California and Michigan have already banned the cloning of humans.

Autosomal Recessive Autosomal Dominant
1,092 wordsEhlers-Danlos syndrome (EDS) is a rare inherited group of connective tissue disorders characterized by defects of the major structural protein in the body (collagen). Collagen is a tough fibrous protein that plays an essential role in binding, holding together, strengthening, and providing elasticity to bodily cells and tissues. There are six major types of EDS that I will discuss, however I will only go into detailed discussion on two of the six types of EDS. The two major types of EDS are Clas...

Factor Viii Factor Ix
1,119 wordsIn the human body, each cell contains 23 pairs of chromosomes, one of each pair inherited through the egg from the mother, and the other inherited through the sperm of the father. Of these chromosomes, those that determine sex are X and Y. Females have XX and males have XY. In addition to the information on sex, the X chromosomes carry determinants for a number of other features of the body including the levels of factor VIII and factor IX. 1 If the genetic information determining the factor VII...

Human Immunodeficiency Virus Cd 4 Cells
2,076 wordsHuman Immunodeficiency Virus The topic of this paper is the human immunodeficiency virus, HIV, and whether or not mutations undergone by the virus allow it to survive in the immune system. The cost of treating all persons with AIDS in 1993 in the United States was $ 7. 8 billion, and it is estimated that 20, 000 new cases of AIDS are reported every 3 months to the CDC. This question dealing with how HIV survives in the immune system is of critical importance, not only in the search for a cure fo...

Bovine Spongiform Encenphalopathy and its human form, Creutzfeldt-Jakob disease, better known as mad cow disease, are new kinds of diseases that appear to be unstoppable. Mad Cow disease is caused by a mutated chain of proteins in a strand of DNA. Because it is neither a virus nor a bacterium, the protein chain has been named a prion. What happens is still unknown, but the theory is that an animal ingests a mutated...
