By modifying the DNA of germline cells, it becomes easier for the modified DNA to be inheritable (Starr, Evers, & Starr, 2013). While introducing the foreign DNA, it is necessary to consider only those that have the capacity to differentiate into different cells of an adult animal. Besides, the embryonic stem (ES) cells and cells of embryos at very early stages might also be considered for the process of creating genetically modified animals. Even though such cells are post-zygotic, they clearly represent a development phase characterized by incomplete separation of the germline and the soma (Starr, Evers, & Starr, 2013). In essence, such cells usually have the capacity to give rise to both the germline and somatic cells. Apparently, a transgenic animal is normally produced when a foreign DNA molecule is introduced into the cell of an animal through artificial means. The transgene (the foreign DNA molecule) may contain just one or several genes. The transgenic animal produced upon inserting a transgene into the already fertilized cells or oocyte from the early embryo, will be able to transmit the foreign DNA in its germline (Starr, Evers, & Starr, 2013). ...
Incidentally, gene targeting has only been possible in mice while efforts to employ it in other mammals have proven futile (Forman, 2010). The design of several new animal of human disease has been necessitated by the ability of the transgenic mice to perform specific changes in a prearranged or predetermined gene via gene targeting. In addition, other experimental approach that involves genetic manipulation of various animal species has highly influenced the genetic engineering procedure (Forman, 2010). The somatic cell nuclear transfer procedure has ushered in a new era in mammalian genetics. For the first time in history, the procedure approved the cloning of an adult mammal. Social and Ethical Implications Various social groups have come out as the strongest opponents of the efforts to adopt the genetically modified animals. For example, different religious groups consider GMOs as a gross violation of the fundamental tenets that have kept society moving (Nelson 2001). Incidentally, many of the religious faiths believe in creation. However, a scenario where man seems to have the powers to create or even modify an animal generally violates the values, ethics, and morals associated with the society. Today, most scientists are finding it much easier to interbreed and genetically manipulate the organism following the discovery of DNA. In essence, biomedical scientists can now build animals at the microscopic level (Nelson 2001). This scenario goes against Christian or even the Islamic faith as they always believe the power to create organisms is a reserve of the Supreme Being. On social grounds, vets now find it easier and even economical to treat ...Download file to see next pagesRead More

Genetically Modified Organisms

...of preeminent resolution for human health problems. In this case, biotechnology has led to establishment of technique through which organisms are modified genetically; in fact, this is as one of its applications. Moreover, biotechnology has been applied in the field of food development, whereby new properties are introduced into the genes of animals and plants to increase their productivity and resistance to pests or diseases. 2. Applications of GMO a. Traditional breeding Conventionally, plant cross breeding involved selection of species with desired properties among the offspring. In fact, crossing was aimed at obtaining a fertile offspring. With introduction of biotechnology, a desire...

Genetically Modified Food

...?Client’s 29 November Every human being is dependent upon certain basic necessities; the most basic of them all is food, shelter and clothing. Food is extremely important for any human being to survive, poverty and hunger still exists in the world and it’s a real shame for all those people who are doing very little about this. People in a comfortable position must contribute extensively to eradicate Poverty only then will the world become a better place to live in. There is a severe shortage of food in African countries, people die in the Dark Continent because of this shortage of food, genetically modified food is really useful and it can save many a life in Africa and all across the globe where poverty...

...such as the toxin genes, Bt toxin extracted from Bacillus thuringiensis found in soil and introduced into the DNA of crops so as to make the crops produce specific toxins that kill the larvae of insect pests (Carter, Moschini & Sheldon 7). This would make such crops insect resistant, IR. The genetically modified Golden rice has its Vitamin A content increased. Future of GM crops According to the WHO, the future of genetically modified crops would encompass development of more crops resistant to drought and with increased nutrient amounts. The technology would be extended to animals with fish species modified to enhance their growth and...

...to children and pregnant mothers. However, after some years, the production of genetically modified food products faced strong opposition from world organizations. The organizations argued that the food products caused serious effects on the health of human beings and even animals. By the year 2010, there was a decline in the production of genetically modified food products. This documented research paper discusses about groups, organizations and societies that have previously given their perspectives about genetically produced crops. The paper also discusses the proposed methods of addressing the problems caused by...

...Critical review on the paper "Evaluation of the sensitization rates and identification of IgE-binding components in wild and genetically modified potatoes in patients with allergic disorders" The ABIC Manifesto, in large extend, explains the necessity of genetically modified (GM) foods. With the growth of the human population, which is "estimated to reach 9 billion by 2040, and with the small but steady decrease of agricultural land (around 70 000 km2 annually)"3, the GM food plants seem like the most effective measure to counter these problems. Nevertheless, there have been serious objections to the manufacture and distribution of GM foods, especially since "1993,...

...Assignment DQ 2: Genetically modified food Genetically modified (GM) food has been at the center of academic debates regarding its advantages and disadvantages, and its effect on the environment. Advantages As the world population is poised to double to 12 billion by 2050, GM food is widely expected to meet the challenges by : 1. Better pest-resistance, by reducing the requirement of insecticides and herbicides, thus increasing food yield naturally by reducing losses. 2. Better adaptation to weather and soil conditions : At present crop yields are often lowered by cold weather, droughts and salinity of soil, but developing resistant GM varieties can increase production...

The data also shows that more than 3.7 million of the scientific procedures in 2010 used animals. However, this resulted into an increase of 100 000 animals from the previous year. This includes significant rise of the genetically modified mice, as well as increased use of fish in medical research and basic biological...

...health because modified genes can react with human body and lead to health issues and other types of illnesses. GMC has also been found to produce health defects and organ failures in animal testing (Dona & Nitoyannis, 2009). This is also a significant reason to worry about genetically modified food and crop. Animal testing has showed its dangers and therefore it is only logical to assume that these crops might also pose risk of organ failures in human beings. The Benefits of GMC One of the main benefits if genetically modified crops is that that it can end famine and shortage of food problem from the developing...
