As the modern science is evolving rapidly, the scientists made great strides in genetic engineering. It is a complex process of manipulating of the organism’s genes used for changing the cells or for transferring the genes within or outside the boundaries of species for the purpose of producing new organisms or changing the existing ones. Implementing endonucleases which break the bond within the polynucleotide chain splits the gene from the chromosome. Frankly speaking, it is rocket science and demands the scientists to go to great lengths to achieve the desired results.
The natural method of generic engineering is known all over the ages. Done outside the lab, it is usually used for breeding. For instance, you take two animals of the same species and of different sex and they mate with each other. The method is used for obtaining the offspring with the desired characteristics such as the size, immunity, marking, etc.
Among the advantages of genetic engineering are removing or, quite the contrary, incorporating inherited characteristics as it was mentioned above. What is more, it includes treating hereditary diseases which have been the calamity for breeders for centuries. It can both accelerate the convalescence and develop the immunity. Nonetheless, the most considerable disadvantage of genetic engineering is that it is not exhaustively examined yet. While conducting the research and laboratory experiments, scientists are introducing new genes to the animals which may consequently lead to dire results. Unfortunately, genetic modification is now seen as an insult to nature and existing arrangements.
Fauna and flora both benefit from genetic engineering. In agriculture, it is used with the aim to make the crops resistant to pests and diseases, more adaptable to the existing conditions, and consume less water while growing. In addition, it increases the chances of having a bumper harvest despite the freak weather conditions. Genetic engineering is done in order to cut down costs needed for farming (including money spent on pesticides) and to boost the income. Nevertheless, the disadvantages of implementing genetic engineering in agriculture are quite numerous. First and foremost, the expenditures of farmers rise as they need to buy more fertilizers and spend more money on modified equipment. Second, as soon as it eliminates pollination, which is one of the main steps for fertilization, the ecosystem is being gradually destroyed. Last but not least, herbicide resistance could be transferred to other crops, and farmers will be in need to spend more money on fighting a constant battle against weeds.
Today genetic engineering is used in medicine for curing diseases. Despite serious dangers, it has already led to the elimination of faulty genes and introducing better ones. Making a notable example, with the help of genetic engineering scientists has already learned how to cure visual impairment.
Under the present-day conditions, people speak out against genetic modification as they are of the opinion that it is against the laws of nature and the world we live in. Nonetheless, genetic engineering will be fully accepted by our society as soon as its advantages will prevail.
