What if cancer could be cured by eating a pear? Or if a crop of wheat could be developed so that it never rotted? These may sound like science fiction but they're not as strange as they first seem to be, and may even be reality in the future. Fifteen years ago who would have thought that plants could be created to be immune to pesticides or that it would be possible to create a sheep that is exactly like its parent in every physical way? And yet both of these currently exist due to genetic engineering. Genetic engineering is a developing science that is viewed with a lot of public apprehension. No one seems to be able to explain what genetic engineering is, when it first began, or what the possibilities are for the future of this science.
According to the U.S. Environmental Protection Agency genetic engineering is: “A process of inserting new genetic information into existing cells in order to modify a specific organism for the purpose of changing one of its characteristics” (USEPA 1). Cells are the smallest living things on earth , but all organisms are made up of different kinds of cells. Some organisms are made up of only one cell, but most organisms are made up of trillions of different cells with each cell having its own job within an organism. Some cells make skin, some make leaves, and others make up nerves and brains (Franklin Institute 1). All cells begin the same with no distinction from other cells; at this stage they are called stem cells and are able to develop into whatever form of cell is needed. Inside each cell is a control center called a nucleus that contains the code with the information for the cell's development. This code is written on deoxyribonucleic acid, or DNA, and is stored in packages, or chrom...

Genetic Engineering: The End of Life as We Know It Essay - Prior to 1982, genetic engineering was a relatively new branch of science. Today, scientists have a firm understanding of genetics and its importance to the living world. Genetic engineering allows us to influence the laws of nature in ways favorable to ourselves. Although promising in its achievements, it also has the potential for abuse. If engineering of this caliber were to be used for anything other than the advancement of the human race, the effects could be devastating. If precautions are not implemented on this science, parents might use it solely for eugenic purposes....   [tags: Genetic Engineering Essays] 773 words

Can Genetic Modification Benefit Humanity? Essays - Throughout the course of human history, new technological advancements have always created opposing views, and conflict between the different groups that hold them. Today, one of the greatest technological controversies is over the morals and practicality of genetically modifying crops and animals. Reasons for doing so vary from making them more nutritious to making plants more bountiful to allowing organisms to benefit humans in ways never before possible. Genetic engineering is a process in which genes within the DNA of one organism are removed and placed into the DNA of another, a “…reshuffling of genes…from one species to another” (Steinbrecher qtd....   [tags: Genetic Engineering] 1676 words

Human Genetic Engineering in Beneficial to Society Essay - Even after thousands of years of evolution, the human race is not perfect: it is ravaged by disease and limited by nature. Yet, in recent times, researchers have begun to ascertain an advanced understanding of the underlying genetic code of humanity. The Human Genome Project, now complete, has provided a map of the intricacies in human DNA, allowing researchers to begin looking at the purpose of each gene. When combined with selective embryo implantation, which is used occasionally today to avoid hereditary diseases or to choose gender, genetic discoveries can become a sort of artificial evolution....   [tags: Pro Human Genetic Engineering]

Is Genetic Engineering Ethically Correct? Essay - Over the past few years, genetic engineering has come a long way from its roots. What spawned as just a project for understanding has now become quite powerful. An article written by Michael Riess aided me in gaining some knowledge of the ethical dilemmas faced in the field of genetic engineering. Suppose you and your partner both discover that you are carriers of a genetic defect known as cystic fibrosis, and the two of you are expecting a baby. Genetic screening gives you the opportunity to use antenatal diagnosis to see if the baby will have cystic fibrosis or not (Reiss)....   [tags: Genetic Engineering Essays]
