Finny Told Gene Ready To Enlist War
620 words"I'm almost glad this war came along. It is like a test, isn't it, and only the things and people who " ve been evolving in the right way survive. " Lepper Leppellier said this extraordinary quote in chapter nine. My interpretation of Lepper's quote was, the war had forced the men to abide by the rule of, "survival of the fittest. " From the perspective of the war, Lepper implied that you need to be prepared mentally and physically for war; you also need to adapt to changes and mature to survive...

Duchenne Muscular Dystrophy Muscle Weakness
1,379 wordsMuscular dystrophy is a group of progressive, genetic diseases in which the muscles that control movement degenerate and weaken. In some forms of this inherited disease, the heart and other involuntary muscles and organs are affected too. There are nine types of muscular dystrophy - (1) Myotonic Muscular Dystrophy (2) Duchenne Muscular Dystrophy (3) Becker Muscular Dystrophy (4) Limb-Girdle Muscular Dystrophy (5) Facioscapulohumeral Muscular Dystrophy (6) Congenital Muscular Dystrophy (7) Oculop...

Ultraviolet Radiation Nucleic Acid
1,499 words... these processes has the potential to damage the genetic material, and thus the cell. This in turn could cause cells to function poorly, causing premature aging associated with Werner syndrome. If the DNA damage happened to inactivate tumor suppressor genes or active oncogenes, it might also cause cells to grow out of control and produce cancerous tumors. In fact, there is already evidence that a faulty helicase can cause cancers. Recently a team led by geneticist James German of the New York...

Current Research On Muscular Dystrophy
576 wordsDuchenne's muscular dystrophy is the result of a defective gene on the X chromosome. This gene is responsible for production of the muscle protein dystrophic. Dystrophin is an integral part of the dystrophic-glycoprotein complex which bears the brunt of the force generated during muscular contraction. When dystrophic is not produced, the dystrophic-glycoprotein complex (DCG) is not present. Absence of the DCG leads to tears in the muscle membrane because the muscle membrane bears the force of mu...

Genetic Disorder Heart Muscle
1,543 wordsProgeria is one of the least known genetic disorders. There are two types of Progeria, the only difference being the age group that it affects. The Hutchinson-Gilford Progeria Syndrome is commonly called Childhood Progeria. The second type of Progeria is Werner's Syndrome, which is the adult form of Progeria. What basically happens in this disorder is that age is accelerated seven times faster than that of a normal person. For example, for Hutchinson-Gilford Progeria Syndrome, a child could look...

Hardy Weinberg Genetic Drift
1,115 wordsThe Hardy-Weinberg theorem states that the frequency of alleles and genotypes in a populations gene pool remain constant over the generations unless acted upon by agents other than sexual recombination. For example, take a population of mice that consists of 1, 000 members. A specific allele, albino allele, is recessive within this species. 80 % of the population expresses the normal phenotype- brown coloring, while the remaining 20 % are albino. 640 members of the population have the genotype A...

Gene Therapy Clinical Trial
793 wordsIn 1990, a three-year-old Cleveland, Ohio, girl named Ashanti De Silva made history when doctors infused her with genes to produce an infection-fighting enzyme called ADA that she lacked. A decade later, the ashes of Jesse Gelsinger were scattered on an Arizona mountaintop after the 18 -year-old died of respiratory distress -- essentially, his lungs shut down -- after getting a massive dose of a modified cold virus intended to carry a gene to his cells. Somewhere in between, the promise of gene ...

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...

Million Years Ago 65 Million Years
3,666 wordsIntroduction To Evolution What is Evolution? Evolution is the process by which all living things have developed from primitive organisms through changes occurring over billions of years, a process that includes all animals and plants. Exactly how evolution occurs is still a matter of debate, but there are many different theories and that it occurs is a scientific fact. Biologists agree that all living things come through a long history of changes shaped by physical and chemical processes that ar...

Human Embryo Cloning Vitro Fertilization
1,759 wordsWhat if Cloning Cloning Benefits What if while walking down the street you encountered someone who looked exactly like you? Would you stare in amazement or would your heart be filled with fear? At first some people may look upon the idea of cloning with disgust and question themselves if humans should play God while others would be interested and study the many possibilities that cloning offers. This illustrates the path that cloning has taken over the latter part of the twentieth century. At fi...

Somatic Cell Therapy Germ Line Therapy
3,341 wordsGenetic engineering has been one of the most controversial ethical issues since 1997; when Dolly the first successfully cloned sheep was announced. Dolly has redefined the meaning of? identical twin? ; not only does she look exactly like her mother she also has the same genetic make up. This experiment was not only impossible but unthinkable. Yet, Dr. Ian Wilmut revealed Dolly on February 23, 1997, at seven months old (Travis 1). On the surface genetic engineering may appear to be the solution t...

Year Old Boy Pain And Suffering
1,522 wordsGenetic Genetic Engineering Genetic Engineering Genetic Engineering is a radical new technology, one that breaks down fundamental genetic barriers- not only between species, but also between humans, animals, and plants. By combining the genes of dissimilar and unrelated species, permanently altering their genetic codes, primary organisms are created that will pass the genetic changes onto their offspring's. The field of genetic engineering has the potential to strip the individual privacy, diver...

Genetically Engineered Foods Fruits And Vegetables
1,952 wordsIntroduction The use of genetically engineering in agriculture and food production has an impact, not only on the environment and biodiversity, but also on human health. Therefore, thorough biosafety assessment requires, not only an evaluation of environmental impacts of genetically engineered organisms, but also an assessment of the risks that genetically engineered food pose for the health of consumers. Let us take deeper look at some of the aspects related to genetically engineered foods. Wha...

Creutzfeldt Jakob Disease Mad Cow Disease
1,270 wordsFatal Familial Insomnia Fatal familial insomnia is a genetic disorder. It manifests itself by many symptoms due to the degeneration of a certain part of the brain, the thalamus. The disease also results in the formation of amyloid plaques. This is the build up of a waxy substance made of proteins associated with polysaccharides. The disease is a result of a mutation of a normal protein that is associated with brain tissue. This is the prion protein. In the case of fatal familial insomnia, the mu...

Alcohol Consumption Behavioral Disorders
2,805 wordsWhen one suggests that a behavior is determined genetically, then one horribly oversimplifies the situation, and negates the importance of culture and free will in determining how a person behaves. One behavior that has gained large-scale acceptance as having a partial genetic cause is that of alcoholism. This genetic cause I expressed in terms of risk factor. It has often been noted that the children of alcoholics are more at risk of becoming addicted to alcohol than are other children. in the ...
