How to write on teenage pregnancy

Whether you are writing the short essay on teenage pregnancy or a longer article on this topic, you will find here lots of topics to work with. Let’s see what you can write about the minimum wages regarding the whole country or the region of your current residence. The next thing to look for are the statistical data on the results of the whole country or the world as a whole. What are some interesting numbers about this topic that you can use in your work? Here are some that you can use in your text.

The facts about the teenage pregnancy

As you might already know, the problem of teenage pregnancy has been known since the mid-80ies of the last century. Since that time, there has been a rapid release of transgenic plants with new useful features to the market. In 1982, the first “golden” transgenic plant was produced in the laboratory of the company “Genentech” in the province of British Columbia. And it was a corn-plant-vector called “Tip Top”. The material was donated to the university, and since 1984, transgenic plants have been producing such transgenic plants as corn, soybean, cotton, and canola. Since the volume of these plants is extremely high, and the cost of producing them is extremely low, such methods of genetic engineering are very attractive for the farmer.

The history of genetic engineering of plants is usually counted from 1982, when genetically transformed plants were first obtained. One of the most common methods of transformation is a technology based on processing of tissue with microparticles of gold (or other heavy metals) covered with a solution of DNA. All cultivated commercial varieties of plants are obtained mainly with the help of this method.

Just fill your own fast food restaurant meals with the topping that you want, and you are guaranteed to get a good grade for the assignment. Because as we all know, the easiest way to make a good natural food is to have it all made from fresh, just like the quick cooking methods. To make it more accessible for the variety of students, it is actually the best to make it the simplest way to the highest grade. Just fill your favorite fast food restaurants with the original ingredients, and don’t be surprised by the results! While not completely relying on the fast food restaurants, but eating at normal restaurants might contain some secret ingredients that the mass media should hide in order to advertising these products to reach their desired goals. And the goal of the protein is to simply satisfy the physiological needs of humans while also making the food colorful and appealing to the younger audience.

The modern arsenal of transformation methods is quite extensive and includes such approaches as the introduction of DNA into bare cells (protoplasts), electroporation of cells, microinjection of DNA into cells, virus-mediated infection, and so on.

It’s worth adding in a “Genetic engineering in agriculture” essay that the researchers went further. Since many plants are susceptible to attacks and eating by insects, GE scientists conducted an experiment with the long-known bacterium Bacillus-Thiringiensis which produces a protein. It turned out that it is very toxic for many kinds of insects, but at the same time, it is safe for mammals. The activated protein binds to receptors of insect’s midgut, which leads to pore formation and lysis of the cells of the intestinal epithelium.

The interaction of toxins with receptors is strictly specific, which complicates the selection of the combination toxin-insect. In nature, a large number of Bacillus-Thiringiensis strains have been found. Their toxins act only on certain types of insects. Such preparations have been used for decades to control insects in the fields.

So, you may emphasize in your argumentative research essay on genetic engineering that embedding the protein gene in the plant genome makes it possible to produce transgenic plants that are not eaten by insects. But this method required a lot of work in terms of selecting the necessary strains and creating genetic structures that give the greatest effect for different classes of insects. In addition to the specific behavior of insects, the incorporation of prokaryotic delta toxin genes into the plant genome did not result in a high level of expression, even under the control of strong eukaryotic promoters.

Presumably, this phenomenon arose due to the fact that bacterial genes contain significantly more adenine and thymine nucleotide bases than plant DNA. This problem was solved by creating modified genes. One of the natural genes was excised. Certain fragments preserving the domains encoding the active parts of the delta toxins were added. So, for example, with the help of such approaches, the potato resistant to the Colorado beetle was created.

Cloning of animals

Cloning, in the most general sense, means accurate reproducing of object any number of times. Creation of animals and plants with specified qualities has always been something very tempting, because it meant creation of organisms that are unique and necessary, resistant to diseases, climatic conditions. They may give the necessary amount of meat, milk, fruits, vegetables and other products.

It may be stressed in a genetic engineering research paper written by students that the use of cloning technology implies a unique opportunity to receive phenotypically and genetically identical organisms that can be used to solve various theoretical and applied problems facing biomedic and agricultural arenas, because such work has allowed to partly solution the problems surrounding the laboratory and increasing the production yields.

It is expected that, thanks to the cloning technology, there will be an accelerated genetic selection and replication of animals with exceptional production indices. In combination with transgenesis, cloning of animals opens up additional opportunities for the production of valuable biologically active proteins for the treatment of various animal and human diseases. Cloning of animals, perhaps, will allow to carry out tests of medicinal preparations on identical organisms.
