Essay on Human Gene Therapy - 1696 Words

Human gene therapy Gene therapy is a technique used in attempts to cure or prevent genetic diseases at the molecular level (basically at the source) by correcting what is wrong with defective genes, a good version of the defective gene is introduced into the existing cells. This technique is still considered experimental, only being done through clinical trials. This idea was first suggested during the 1950’s. The basic idea was â€Å"if the basses can be arranged incorrectly then why can’t they be rearranged in the correct way?† A genetic disorder is a disease that is caused by a mutation (change in DNA sequence that makes up a gene) in a person’s DNA. Inheriting a faulty gene can cause susceptibility to cancer and can cause many different†¦show more content†¦Different types of vectors exist. There are two vector systems, viral vectors and non-viral vectors. Viral vectors are viruses; they are deactivated and used to carry DNA to the target cells. Although the v irus is basically harmless it can still insert its genetic material into the target cells and create the proper protein. Examples of viral vectors are retrovirus, adenovirus, and herpes simplex virus. A plasmid is an example of a non-viral vector. A plasmid can be described as a circular DNA molecule. Sometimes to make it easier for them to enter cells the plasmids are packaged inside of liposomes, liposomes are membrane-wrapped packets that transport their contents by combining with cell membranes. Advantages of viral vectors are the following: they are good at entering and targeting cells, some specifically cells certain types of cells, and they can be made to not replicate and destroy cells. Disadvantages are that an immune response can be triggered which may cause patients to become sick and can also disallow the genes to be delivered or can kill the genes, and the size that they can carry is limited so some genes may be too big to fit in a viral vector.

Most commonly, new and functional DNA is put within a vector which is then inserted into the patient. Gene therapy not only treats the problem but treats the genetic issues with a person’s DNA. The genes help to correct or replace the genes that were functioning incorrectly. Gene therapy helps by stopping a protein from functioning incorrectly, giving a protein a different function, giving the protein its normalRead MoreEssay on Human Gene Therapy1921 Words   |  8 PagesHuman Gene Therapy Imagine this, you have just married your college sweetheart this past summer.

Poverty Of The Wealthiest Country - 1940 Words

Poverty in the Wealthiest Country People often say that money cannot buy happiness. However, this statement is not applicable to everyone. Bare minimum financial revenue is actually necessary to provide well-being and happiness. When the concept of poverty comes up, usually the first image in our minds is people living in developing countries such as those in Africa; however, first-world countries are not safe from this issue. According to the U.S. Census Bureau, 14.5% of the United States’ population are living under the poverty line; that is, 45.3 million people struggling everyday to afford essential life items such as food, healthcare, transportation, clothes, and housing in the world’s wealthiest country (Income and Poverty in the United States). Poverty has distressful effects on the poor as individuals and on the society as whole. It poses health and financial hardships on the individual; and threatens the safety and productivity of the society. The root causes can be classified into three categ ories; economic factors being the primary, social and educational factors being the secondary. Poverty is a serious issue that has been traumatizing and spreading despite the efforts being made to combat it. Impoverished people suffer from the lack of jobs and education that would otherwise improve their situation. They are subject to greater physical and mental health risks such as malnutrition and depression.

Economics My Tool, My Inspiration free essay sample

Out of all the courses I have taken I enjoy more those that expand the limits of the mind, increase my awareness of the world and exercise the imagination. The class that does this best is Economics. Not only is it a science of life, business and development, but it is a philosophy with precise tools and universal language that explains phenomena and all quotidian transactions. Economics has helped me grow, expand my interests and catalyzed my decisions for my future and career. The more one knows, the more one feels the need to question and to come up with queries never before thought. As a child I saw the world as an irrational place, dominated by the whims of chance; but basic knowledge of Economics led me to conclude that it was not irrational, just complex. â€Å"Master it I must!† was my war cry after such an important life changing epiphany. We will write a custom essay sample on Economics: My Tool, My Inspiration or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page My throat felt dry for knowledge and the closet-monsters that disturbed my sleep were substituted by unexplainable questions: Why do businesses fail? Why do nations collide? What is this paper with which all my things are bought? Twelve years, money games, various books, two excellent teachers and an infinite amount of answers from my father later; and I can now understand the world with more confidence, but the thirst for answers and explanations remains. The family business and Economics at Harvard Summer School this summer implanted in me the millennial desire of our species to understand. After beginning my transformation into a questioning individual I could not limit the ponderings of my brain. Realizing what other branches of knowledge had to offer me, I became interested in history and the evolution and refining of our society, in languages and literature and the ability to communicate thoughts. I read history for entertainment, fascinated by the ancient Romans and Greeks. I learned Spanish, English, Hebrew and French. The next step was my recognition of Finance, Administration and Accounting- tangents that intersect the crucial points of Economics. The day I reached the age of reason (or my ‘age of Economics’) and recognized the importance of Economics it began to shape my goals and my future. I began to imagine how this knowledge could be applied to the greatest and worthiest cause of all: the wellbeing and development of mankind and society. I excelled in school making the most of my education despite the great obstacles that accompany the life of an immigrant. I had to master my English and adapt to a foreign culture when I moved to the United States in 2003 but I worked even harder in pursuit of my goals. Meanwhile, I started my own small web design business and an expanding non-profit organization Economics is my cause, tool, goal and inspiration. It has made me long to learn, apply and discover. I have found what many seek their entire lifetimes, a purpose, and in the process transcended my previous self and the confines of my understanding.
