Duchenne Muscular Dystrophy Cystic Fibrosis
2,111 wordsWithin the first few hours after conception a phenomenon takes place in the one-cell human embryo that has awed scientists and philosophers for more then a century. The genes of the mother, carried by the ovum, and the genes of the father, carried by the sperm pair up. At that moment, when the paring is completed, the genetic fate of the person-to-be is sealed. The sex, color of eyes and hair, the height, blood type fingerprints, shoe size- indeed all physical and chemical characteristic are irr...

Tay Sachs Genetic Disorder
590 wordsThe genetic disorder I have looked at in this scientific statement is Tay-Sachs disease or TSD, a serious, inherited fatal brain disorder. The disease is named after Warren Tay, a British ophthalmologist who first described the disease in 1881 and a New York neurologist, Bernard Sachs; who first described the cellular changes and the genetic nature of the disease in 1887. This rare hereditary disease is caused by a genetic mutation that leaves the body unable to produce an enzyme; a protein that...

Tay Sachs Disease Sickle Cell Disease
663 wordsEach year a number of children are born with biological defects that impair normal function. For THREE of the following conditions, discuss such aspects as the biological cause, the methods of treatment and possible means of detection and / or prevention. One lethal disorder inherited as a recessive allele is Tay-Sachs disease. This is caused by a dysfunctional enzyme that fails to break down brain lipids of a certain class. The symptoms usually become manifest a few months after birth. Some sym...

Genetic Disorder Tay Sachs Disease
579 wordsMy name is Put your name... and I am a carrier of Tay-Sachs Disease; my partner is also a carrier of this disease and our child is affected with Tay-Sachs Disease. Tay-Sachs Disease is a recessive genetic disorder which contains harmful quantities of fatty substances called Ganglioside GM 2 which harms the nerve cells in the brain. This disease mostly affect infants. The only way for a baby to be affected with this disease is when both of the parents is a carrier of this disease. There is a good...

Natural Selection And Diseases
1,383 wordsCystic fibrosis, Tay-Sachs, and hypertension are three very different, yet deadly diseases. The question arises how these diseases have survived for so long. Three articles attempt to uncover the mystery behind these diseases. It has been found that there were benefits to each of these diseases, which allowed the allele to remain in the community for such a long period of time. Natural selection plays a large part in the success of these conditions. First, cystic fibrosis has been found to be pr...

Some of these enzymes break down proteins, others attack fats, and still others disassemble the nucleic acids that make up DNA and RNA (Bourne, 1992, p. 123). Lynosomes don't always work right. When they fail, the result can be catastrophic disease. In Tay-Sachs disease, for example, victims have inherited a faulty gene, which leads to a defective enzyme or no enzyme at all. As a result certain undigested molecules accumulate in the lysosomes, gradually lead...

The person that wanted to do this was H H Goddard. He brought Binets scale to America from France but he manipulated it to interpret innate intelligence. Goddard believed that the American population was at risk from the swift reproduction of the feeble-minded and from immigration. He also came up with a scale th...

Duchenne Muscular Dystrophy Sickle Cell Anemia
965 wordsHemophilia Hemophilia is the most famous bleeding disease. In this disease, there is a lack in the amount of a certain protein called anti-hemophilic globulin, or Factor VIII, in the blood. Factor VIII is extremely vital in the clotting of the blood. Because of the way hemophilia is inherited, only males can contract this disorder. Hemophilia is passed from generation to generation by female carriers. In the United States 1 male in every ten thousand has hemophilia. Symptoms appear in childhood ...

Tay Sachs Cystic Fibrosis
842 wordsGenetic Disorders Genetic Disorders Introduction Genetic Disorders are medical conditions that are caused by an error in a persons genes. Some of them appear as a birth defect, while others do not become distinct until later in life. Genetic disorders can range from those that cause death to those that produce only mild problems, such as color blindness or an extra pinky. Scientists have distinguished more than 9, 000 genetic disorders. Some are exceptionally rare while others are quite common. ...

Tay Sachs Disease Autosomal Recessive
812 wordsThis condition, Tay-sachs TAY-SACHS DISEASE This condition, Tay-Sachs Disease, is due to the reduction of a key enzyme. This missing enzyme is hexosominidase and is commonly referred to as Hex A. When this enzyme is missing in lipids (fats), GMZ ganglioside accumulates in inert cells. Hex A is key and is needed to break up and regulate lipids. When GMZ builds up in the neurons, the functions of the nervous system are affected. This leads to mental retardation, damages in the nervous system, and ...
