Gene manipulation in modern society
Genetic manipulation was first introduced in agriculture. It is used to insure insect resistance and allows farmers to grow more crops in a shorter amount of time. Also, because of an increase in population, the use for genetic mutation has begun to grow. There are just too many insects and weeds to obtain a maximum amount of crops.
However, gene manipulation has a number of consequences. Food manipulation through genetic engineering can become a dangerous and even a toxic substance for the metabolism causing new allergens in foods that previously were naturally safe. For example, a manipulated bacteria used to produced large quantities of a dietary supplement, triptophane, caused 27 deaths and 1.500 disabilities in the United States (in 1992)
Methods of genetic manipulations
In 1973, scientist discovered that it is possible to combine genetic material into different organisms. By taking certain genes from one animal and putting them into another, you can produce an animal that has characteristics from both. For example, scientist took the gene that produces horns from a goat and injected it into a lamb. The lamb later began to grow horns. When you inject a gene from an animal that prevents certain human diseases into a human, the gene protects the human from getting the disease as well.
This method, however, does have its disadvantages. It is unpredictable whether the immune system will actually take the gene or that the gene will land in the right place. The gene could land randomly along the cells chromosome, causing it to work poorly or not at all. It might even land in the middle of another essential gene, crippling it or even killing if off.

- Gene Therapy Imagine yourself being a parent of a young child suffering from a horrible disease in which you now know to be genetically inherited. This disease is caused from the genes that you and your partner passed on to your child. Now lets say, you can treat this disease or may even be able to cure your child of this disease by altering, modifying, or replacing the genes that cause this disease through a process called gene therapy. Would you do it. I think most of us would answer yes. The option of being able to help our child several years ago may not have seemed possible.... [tags: Biology Science Genetics Technology Essays]

- Long standing arguments against the theory of natural selection stem from the occurrence of incipient structures and complex traits in organisms despite the seemingly stochastic nature of mutations. Many complex adaptations observed in nature today are thought to have arisen from less complex ones with simpler functions, therefore these characters are thought to have been “pre-adapted.” In order to go from a simple to a complex structures there must have been a transitional phase, where the two structures function simultaneously or where the new function is assumed without interfering with the old function....

- What Makes a Psychopath. Depictions of psychopaths today have become exaggerated based off of what you see in movies and films. The psychopaths in movies are believed to be dangerous or have an anti-social personality disorder. Not all psychopaths can be defined in that manner. Psychopaths are identified as people who are emotionally unstable. They are ultimately suffering from a chronic mental disorder with abnormal or violent social behavior. There have been studies ultimately wondering if a psychopath is born, or is it raised.... [tags: mental illness, manipulation, emotions]

- Genetic 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 to all of society’s ills and the worlds problems.... [tags: Genetic Reseach Manipulation]

Genetic enhancements, in the aspect of beauty will become a valued focal point in the medical industry (Tucker). The desire for enhancements are slowly increasing in demand as media pressure society for such behaviors, in which will lead to the rise for individuals to meet the expectations of the society’s beauty. In fact, as beauty is emphasized around the world which creates even more pressures to lean towards the abusive of enhancements to fit in.... [tags: negative effects on babies, genetic engineering]

- Many citizens strive to make our society a better one for everyone. By attempting to filter out genetic inferiorities, many believed there were positive effects to the idea of eugenics. Many historic eugenicists thought society would be better by preventing the births of people afflicted with these inheritable diseases. This sterilization movement was very flawed in the early 20th century. Much of the data collected and methods used by eugenicists determined why certain individuals were malleable to a society....

- Stereotyping, which can be used positively and negatively, is something everyone uses every day; it is found in our humor, how people describe one another, and beliefs. People stereotype without knowing it; it is a way we use to help us understand a group. The problem with stereotyping is that it’s a self –opinion about a group, not an individual. Everyone has their own unique and distinct personalities, just as everyone has their own fingerprints so it is unfair to be judged quickly by people who do not know others as an individual....

- Throughout time, man has always questioned science. Man has been curious about life, space, our bodies, and our existence. Man has gone as far as to the moon, and cloning. Everyday there are new developments being researched. Along with these developments come the people’s opinion. Many people question the positive outcomes and negative outcomes of procedures such as gene manipulation, cloning, in vitro fertilization and fetal tissue implants. To this day, scientists are researching and developing ways to “design” their children by selecting their sex, height, intelligence, and color of eyes.... [tags: essays research papers fc]

Another method is a kind of cut and paste approach. Instead of taking a gene from another living being, scientists will make a sort of upgraded gene. The "bad genes" are then extracted and the advanced ones are put in its place.
Unfortunately, this method is not fully perfected either. It's common that the body will reject these new genes. When the body finds something new, the immune system most likely to attacks it. Also disturbing certain genes can cause the body to shut down. The body can't function when something is missing. So unless the gene can be replace in time, the result is bodily shut down, which can cause sever brain damage.
The last method is one scientists most prefer. Adding genes and leaving the original set alone is much safer. To do this, the scientist would have to build an artificial chromosome. Then, instead of the body having a gene of its own, it would carry a pair of genes made to change or develop a certain characteristic or health issue. Of course these extra sets of genes would be able to pass from one generation to the next. This would leave future generations with their normal chromosomes and the extra pairs. A human body is only meant to have 23 chromosomes; this method would result in way to many.
Nevertheless, scientists are working on a way to prevent this from happening. They are trying to make these genes only available during childhood. When the owner becomes an adult and is ready to have children, the extra pairs of chromosomes will simply disappear. However, this is not simplistic and reality is much harder then its sounds.
Causes from gene manipulation
Gene manipulation, also called human germline engineering, refers to the egg and the sperm. Scientists plan to change to genetic make up of a person at the moment of conception. Although, this mutation can go as far as certain human attributes like appearance and personality, scientist reassure the public that it will only be used to prevent disease.
Unfortunately, the world doesn't work this way. In countries like Canada or Great Britain, the science of genetic engineering is more widely accepted. Of course, this type of research requires large sums of money. This circumstance would lead to certain parents paying for this research and then using it on a child of their own.
According to researcher Princeton Silver, this will cause an even larger gap between classes. There will be those who can afford the designer chromosome and those who are left with natural selection.
Furthermore, societies that favor boys over girls, like China or India, are already out of balance. This will definitely cause a distortion in human population and possibly gender-role stereotypes in modern society.
Overall, is society really ready for such huge leaps in human biology? Changing natural selection and nature its self, can come with serious consequences. As Tuft Krimskys says, "We know where to start." The harder question is this: "do we know where to stop?"
