Sickle Cell Anemia Essay

the body lacks a kind of glucose, specifically Glucose 6 Phosphate Dehydrogenase (G6PD) in the blood. G6PD is prevalent in every cell of the body, especially in red blood cells, where it cleans up free radicals in the cells. Free radicals are chemical elements looking to pair up with other chemicals, but can cause chemical reactions within cells that cause premature cell death. Free radicals disrupt cellular chemistry, and are thought to be a major cause of aging. In a normal body, there

cause of MS is unknown but it affects women more than men. Scientists believe the disease is triggered by certain environmental factors to individuals who are genetically predisposed. The antigen present in the myelin and nerve fibers that immune cells target is still unknown. Damaged myelin forms scar tissue (sclerosis). There is no cure for MS but individuals with MS seek treatment to help prevent the degradation of neurons.

Embryonic Stem Cells Why should people suffer from diabetes, Alzheimer’s, sickle cell anemia, leukemia, and plenty of other degenerative diseases while the cure lies in our hands? After James Thompson, a developmental biologist, reported that he had derived the first human embryonic stem cell line (Thomson), the potential of curing degenerative diseases was revealed. Ph.D. holder and deputy director of FDA’s office of Cellular, Tissue and Gene Therapies, Stephanie Simek, explains that stem cells are unspecialized

information. Important information can be deleted, swapped, or completely altered. It is because of these changes in chromosomal DNA that changes in species come about. Genetic disorders are the negative effects of mutations in genes. For example, Sickle-cell anemia is a blood disorder which

There is however no scientific evidence which suggests that people with sickle cell will become drug dependent if their pain is treated with narcotics. A local hospital changed its entire standard method for treating sickle cell patients based on the assumption that people were “becoming too addicted to pain medication”. Coping with Sickle Cell Disease varies among different age groups. Individuals aged 18-30 were found to seek acute care most frequently and

occurrence when an individual travels to a foreign place and passes his or her genetic material into the new population. Mutation is the process that changes an individuals DNA and can affect the organism in any aspect. B. The incidence of sickle-cell anemia is an excellent example of a "balanced polymorphism" because "It illustrates balanced polymorphism because carriers are resistant to malaria,

I am a first-generation daughter to Nigerian immigrant parents. As one may imagine, the journey from a populous country in West Africa to the city of Dallas, Texas can be a strenuous task to overcome. In spite of this, my parents both collectively made the difficult decision to leave their families in Nigeria for the brighter prospects and array of opportunities the American education system has to offer. Because of the obstacles my mother and father have endured in their past, they have ensured

heterozygote was a balanced polymorphism. It was also a fitness trade-off: carriers could pass on the sickle-cell allele, but they received immunity from malaria. (Larsen 102) In other words, if the malaria happened in the society like Gattaca, the valid people totally could not resist it because sickle-cell genes are selected out already from their body. And, only invalid people who carrying the gene for sickle-cell disease are protected from malaria. Consequently, the designer baby is very dangerous for the

normal after all. The son was diagnosed with Sickle Cell Anemia, a genetic disorder that affects the shape of red blood cells. Without treatment, Jim would have a high chance of dying. However, Jim was given a second chance to achieve normality like his mother always wanted with the help of genetic engineering. Genetic engineering, “the process of manually adding new DNA to an organism” (Lincoln 1),can be used to treat genetic disorders such as sickle cell Anemia, but there is a large percentage of people
