What is nothing more than a simple and understandable acknowledgement of the importance of keeping the nature and animals species alive instead of trying to protect and protect species, which simply live by the rules and norms of nature. In this regard, the theme of life and death is intrinsically close to consciousness.
When writing a positive review for essay that explains how animals are important, you can find an example of argumentative essay on animals being used for research purposes. This kind of paper is designed to evaluate the results of the whole researches using animals for their experiments, as well as the results of individual experiments conducted in detail.
Contents of life and death essay
Although the topic is new, there are still many unsolved problems in the field of human physiology and medicine. The first of them is the problem of the underestimation of the physiological and psychological costs of keeping animals in laboratories.
In order to even begin to address this problem, it is worth beginning with the discussion on anatomy and genetics. This is a subject which, however, is still unsolved in most countries of the world.
The fact that modern medicine relies on animals, especially in critical situations, exposes them to increased danger. As a result, the patient, having consumed the normal diet, may die due to a toxic reaction. The genes of some cells of the organism have been radically changed in order to change the genetic characteristics of viruses and cells. This process is already going on, for example, a large amount of transition peptides have been introduced into animal cells.
What is known about DNA technology is that it is a reliable method for obtaining recombinant DNA unifying sequences of any origin, including, in particular, excellently expressed genes. With the help of DNA technology, scientists were able to correct the largest non-standard errors in the genes of bacterial cells. Now, using this method, any amount of leukocytes is obtained.
The main advantage of DNA technology is that it allows to take the nucleus of the gene and insert it into the cell. After a while, it will be easy to obtain the relevant gene, and then, using the appropriate gene, to modify the cell. Thus, it is already known that the cell nucleus controls the development of the embryo.
Already for many years, the technique of recombinant DNA has led to the fact that the transcription of genes is more local in the nucleus of the organism than in the expression of them in the body. Thus, injecting a recombinant DNA gene into a cell, the bacterium which has been expressed will quickly change its genetic characteristics.
A useful advantage of this method is that, in the future, when creating a large amount of transgenic plants, the nuclei of the plants will be able to store all the necessary information, and when cultivating many varieties of plants, the nucleus of the herb will be able to provide all the necessary services.
Useful tips for writing the first essay on genetic engineering
The underlying science of genetic engineering is just a young area of knowledge which, however, was improved over the last 10 years. During this time, there were many problems in the sphere of genetic research, but progress has been steady. In 1996, the first genetically engineered plant was created. The company “Genentech” presented a corn plant with which it is possible to transform the normal, cultured corn into a transgenic one.
The technology of recombinant DNA realized an unconventional “protein-gene” approach called “reverse genetics”. You may explain its essence and benefits in a short essay on genetic engineering. A protein is isolated from the cell. The gene of this protein is cloned, modified by creating a mutant gene encoding the altered form of the protein. The resulting gene is introduced into the cell. If it is expressed, the carrying cell and its offsprings will synthesize the altered protein. Thus, it is possible to correct defective genes and treat hereditary diseases, as well as various diseases and disorders.
With the help of genetic engineering, animals which have useful traits and are resistant to viral attacks were created. For example, a microinjection of a recombinant DNA containing a bovine somatotropin gene into a rabbit zygote made it possible to create a transgenic animal with a hyperproduction of this hormone.
It is even difficult to predict all the opportunities that will be realized in the next few decades. Now let’s consider the fields of practical application of genetic engineering.
Information for essay on genetic engineering in food production and medicine
Twenty years ago, plant biotechnology lagged in its development. But it’s worth mentioning in genetic engineering persuasive essay that, over the last 10 years, there has been a rapid release of transgenic plants with new useful features to the market. In 1996, in the US, transgenic plants occupied an area of 3 million acres. In 1997, the area increased to 15 million acres, in 1998 – to 60 million acres, and in 2000 – to 80 million acres.
