Get Access Genetic Engineering Essay Sample Genetic engineering has been an controversial topic due to the many sides that it has an impact on. Some say that genetic engineering can aid the environment, since genes could be manipulated in trees to absorb more CO2 to reduce the threat of global warming- while others also in some religious beliefs think that the humans should not have the right to manipulate the laws and course of nature.
In this essay, I will contrast the overall impact it has brought upon society and come to a conclusion. Genetic engineering as the direct manipulation of DNA by humans outside breeding and mutations has only existed since the s.
The key event to modern genetic engineering began in the s when Paul Berg created the first recombinant DNA molecules, and when Herbert Boyer and Stanley Cohen created the first transgenic organism by inserting antibiotic resistance genes into the plasmid of an E. Genetic engineering is a complicated procedure which is divided into 7 steps; Isolation the gene, Construction, Gene targeting, Transformation, Selection, Regeneration and Confirmation.
The gene to be inserted into the genetically modified organism must be chosen and isolated for identification. After the gene is isolated, the gene is inserted into a bacterial plasmid.
At the construction stage, the gene can be modified for better effectiveness, and to control the location and level of gene expression. Then, gene targeting uses homologous recombination to target desired changes to a specific endogenous gene.
Next, in the transformation stage, the genes to be inserted are cloned into a binary vector, which when constructed, will naturally insert the genetic material into the plant cells.
In the regeneration process, often only a single cell is transformed with genetic material the organism must be regrown from that single cell. Lastly, in the confirmation stage, further tests are taken to confirm that the gene is expressed and functions correctly. Genetic engineering had had a positive impact on society with its variety of applications.
Agriculture and medicine are the two areas which make use of the genetic engineering techniques the most.
In gene therapy, genes are used to treat or prevent diseases, effectively replacing the use of drugs or surgery. The Human Genome Project is an international scientific research project with the goal of identifying genes of the human genome from both a physical and functional standpoint.
The project allowed for much deeper understanding in the human body, which creates opportunities to develop and enhance medicines and even discover cures for diseases. Genetic modified foods include crops, vegetables and fruit that have been created using genetic engineering methods. They are more productive and have a larger yield while also offering more nutritional value and better flavor, which means it has an advantage over natural foods.
The fact that they are more productive means that it is more quantitative compared to natural foods, meaning it would lower the food prices for countries that has genetically modified foodswhich in the long term would indefinitely balance the wealth spread between the rich and the poor.Genetic Engineering is a direct human manipulation of an organism’s DNA structure.
As intricated as it seems, it’s a technology that has been used for decades, . Genetic engineering is a powerful and potentially very dangerous tool. To alter the sequence of nucleotides of the DNA that code for the structure of a complex living organism, can have extremely ill effects although the potential benefits can be huge.
