Abstract
This paper discusses an experiment that used recombinant DNA technology and explains that the hypothesis for the experiment is that, by using recombinant DNA technology, specific DNA fragments can be cloned, in this case from a mouse liver cell, by differential centrifugation to obtain high purity DNA fractions. The paper describes in detail the materials and methodology of the experiment as well as the results and the calculations. The paper concludes that the experiment supports the hypothesis by the fact that five colonies were created, which contained the specific 2.0 DNA fragment, signaling that the bacteria contained the desired insert-vector molecule.

"Western Blotting of the samples was performed also performed. There are about 1012 antibody molecules in the immune system. The major function of the immune system is to protect the being. Antibodies are produced when outside organisms enter the body. The antibodies join with the foreign molecules and neutralize them. Antigens are the molecules that cause antibody production and are usually similar to proteins. Epitopes are the features that are recognized by the antibody."

"Genetics today is on the cutting edge of biological science, and scientists working in this area are involved in a wide variety of pursuits that will have profound implications for our future on this planet, with projects including the creation of new biologic entities, curing diseases, manufacturing synthetic versions of biologic substances, identifying different genetic codes and what they do, and perhaps finding a way to control that genetic information to produce animals with certain characteristics or without certain characteristics, including greater strength, resistance to disease, and a higher yield in meat, eggs, dairy products, or whatever they provide. Geneticists have already accomplished many of these things with grains, plants, and even certain farm animals. They are addressing disease through the creation of new strains of bacteria by means of recombinant DNA ..."

Abstract
This paper describes an experiment designed to refute or support the hypothesis that using recombinant DNA technology allows for the cloning of specific DNA fragments. The paper then analyzes the results of the experiment and concludes that the hypothesis is supported by the fact that five colonies were created that contained the specific 2.0 DNA fragment, signaling that the bacteria contained the desired insert-vector molecule. The paper includes several tables, graphs and images.

Discussion

From the Paper
"The purpose of the second part in the recombination of DNA was to isolate plasmid DNA from E. coli harboring pUC18 plasmids with -DNA fragment inserts and cut the DNA with HindIII. Bacteria from Transformation 4, both blue and white colonies, were to be taken for inoculation. The white colonies could not be obtained because they are satellite colonies that grow from enzyme excretion. The samples were obtained from already prepared liquid forms of the white colonies."

Abstract
This paper explains that, for many centuries, farmers fought pests using everything from usual plant-breeding techniques to chemicals, such as pesticides and herbicides; but, as new chemical treatments increased health and environmental concerns, gene modification became the agro-scientists tool for advancing molecular biology. The author points out that over 40 plant varieties have completed all of the federal requirements for commercialization as per the FDA and the United States Department of Agriculture (USDA). The paper explains that, although customers in the U. S. are accepting GM foods, customers in Japan are beginning to show a strong liking for unmodified fruits and vegetables in supermarkets offering both GM foods and unmodified foods.

From the Paper
"Genetically modified foods (GM foods or GMF) provide opportunities to swiftly enhance crop nature such as yield, pest resistance, or herbicide tolerance, which is not successful with conventional methods. From the predecessor to plastics to consumable vaccines, GM crops can be molded to make completely artificial substances. The methods of modern genetics have made it probable for the direct action of the genetic makeup of organisms. Using genetic engineering, plants from wild relatives, other distantly related plants, or almost any other organism can be relocated with simple genetic qualities into the crop."

Abstract
This paper looks at the use of mitochondrial DNA (mtDNA) in tracing human evolution. The paper explains that mtDNA is maternal, and non-recombinant, making it a useful tool for looking back at ancestral lines and tracing them to the first modern human. The paper considers the two hypothesis for this: the African replacement hypothesis and the multi-regional hypothesis.

From the Paper
"Reconstructing human evolution is now done using genetic markers on mitochondrial and nuclear DNA to trace the relationships and origins of human populations. Because all mitochondrial DNA (mtDNA) is inherited through the maternal cytoplasm variations in mtDNA provide evidence of maternal lineage. There is no DNA recombination occurring in mtDNA so the only changes from one mtDNA to the next are due to mutations in each sequence derived from a common ancestor. Polymorphisms are common in the non-coding regions of mtDNA with an estimated..."

Abstract
This paper studies the genetic engineering process of cloning. The paper opens with a discussion about genetics and the author's assertion that cloning humans will happen in the near future. Next, the paper studies the process of cloning, which naturally occurs botanically. The paper then turns to cloning among animals and -- ultimately -- human beings. After an analysis of recombinant-DNA formation, the paper concludes with a review of the debate over the morality of cloning.

From the Paper
"Some examples of cloning from nature are the primary reproductive mode and supplementary reproductive mode. The primary reproductive mode occurs in species whose reproduction is strictly asexual; each population consists of one or more clones, depending on the number of individuals in the colony there was to start. Such species include all bacteria and blue-green bacteria, most protozoans, algae, some yeast, and even some higher plants and animals, such as dandelions and flatworms. Supplementary reproductive mode occurs in some algae, which reproduce sexually and asexually. Those individuals formed by asexual reproduction, called zoospores constitute a clone. In the club mosses and some higher plants, a runner, or stem, grows horizontally along the surface of the soil and at intervals produces roots and upright stalks. When the sections of stem between stalks disintegrate, the separated individuals constitute a clone."

Abstract
In this article, the writer notes that people have known since time immemorial that it is possible to breed animals and plants to enhance their desirable characteristics and to 'breed out' their undesirable traits. In addition, the writer points out that many have argued that, since it is possible to breed horses for speed or stamina, it should be possible to breed human beings for specifically human qualities such as intelligence, kindness, and sociability. The writer discusses that with the advent of the genetics after discovery of DNA and the subsequent development of recombinant DNA techniques, this vision reemerged in a new guise. The writer maintains that because genetic research poses great opportunities for humanity to treat incurable disease and change humanity's negative features, genetic research also hides its many threats such as unexpected and non-predictable results, ethical and moral dilemmas. The writer concludes that society must be aware of the possible uses and misuses that may be made of biotechnology in the future.

From the Paper
"The new techniques provided a way of isolating specific genes and inserting them in the cells of gene-caused diseases such as sickle cell anemia. The inserted gene would then take over from the defective genes. More than 4000 diseases are thought to result from the defective functioning of a gene or a set of genes and if it were possible to identify the location or site of each gene on a chromosome, it might be possible to replace the defective gene by gene therapy or gene manipulation. Scientists have identified some specific gene defects or abnormalities: some of these defects increase the risk of diabetes, others are linked to the risk of manic-depression and schizophrenia, some again result in dwarfism, or terrible disability. Many of the so-called monogenic diseases - those caused by the malfunctioning of a single gene - can now be detected while the embryo is in the uterus. The only alternatives for a woman carrying an embryo with a severe genetic disorder are either to go through with the pregnancy or to have it terminated."

Abstract
Today the advancements in science have made possible the selective study of the individual segments of the DNA of a particular species, to isolate them and to infuse them in the DNA of a totally different organism. The paper shows that genetic engineering can be viewed as a breakthrough in the study of organisms that effectively disintegrates the distinctions that exists in the different species of the world. The advancements in recombinant DNA technology have expedited the research in genetics. This paper analyzes the subject of genetic engineering and in the process analyzes its pros and cons and its future implications.

From the Paper
"Genetic engineering is a fast growing field, which is rapidly removing the species boundaries. Genetic engineering appears to be the solution for all genetically inherited disorders. With the rapid advent of bio-chip technology we are in for a paradigm shift in medical diagnosis. Gene manipulation is nothing short of altering the fundamental life code and unless sufficient care is exercised it may lead to disastrous consequences. With all the proposed advantages genetic engineering is still a debatable subject with the scientific fraternity sharing mixed opinion on the subject. Unless we are very sure about the safety and the precautions of inter-species transfer of genetic material there is every chance that we might end up endangering ourselves and other forms of life on earth. Leaving alone the other issues the very thought of playing with nature is quite unsettling."
