Pros And Cons Of Genetically Modified Animals

Should we genetically modify animals to be sold as pets?
Genetically modifying an organism is the process of altercation of genes to change the organism into the preferred organism; a genetically modified organism (GMO). Inside genes are DNA (Deoxyribonucleic acid), which are made up of a nitrogen base, a sugar group and a phosphate group (PO4). DNA is what defines the traits of an organism. Scientists are now trying to use this knowledge to switch or add DNA to an organism to have ‘better’ traits. The techniques used to edit a fragment of DNA are bacterial enzymes that are like “molecular scissors.” This most recent and most efficient way of genetic manipulation is called CRISPR-Cas9, because Cas9 is the enzyme used to edit the genome.
There are many advantages to GMO’s. One of the main reasons is GMO’s can improve on the species of food or animal for better use. With crops, such as corn, a gene/DNA that allows more resistance to insects could be added to the corn to make the growing process easier creating better output. (Figure 1). Similar to food, animals such as salmon are now being genetically modified to grow faster and larger which help improve the overall food supply. …show more content…

Currently, there is only one genetically modified animal that is being sold on the market as pets. GloFish, created by Dr. Zhiyuan Gong and marketed by Yorktown, are genetically modified fish sold online and at stores (Figure 2). They were created when Gong extracted a green fluorescent protein, which is extracted from a jellyfish, and inserted it into a zebrafish embryo. They currently have fluorescent tetra, barb, danio and rainbow shark in a variety of colours selling online and at their

However, GMO's are controversial because chemicals are used to alter the genetic information of a crop. Those chemicals can increase the risk for certain illnesses, such as diabetes and cancer. GMO's are meant to be the perfect organism, however many factors can go wrong with so much genetic modification since its going against nature (Food Policy Institute 2003). The process of how GMO's are created is through the help of gene transfer technology. The desired gene from another organism is placed in the other organisms genome

Pros And Cons Of Genetically Modifying Animals

236 Words | 1 Pages

Genetically modifying animals to grow quicker and larger animals is ethical to a certain extent. In a previous TED talk, we learned that there is a vast difference between the ratio of food production and human reproduction, so the quantity of food that is being produced is insufficient for the human population. For this reason, genetically modifying animals would be ethical because it provides a new form of increasing the production rate of food and decreasing hunger. However, the ecosystem can be disturbed by genetically modifying an animals and the process may be harmful to the animal. It is not ethical to create organism to have characteristics that an individual desires.

For thousands of years humans have influenced the genetics of animals and plants through selective breeding and cultivation of crops. Following the introduction of genetic engineering in 1972, the technology has been utilized in multiple industries - improving the standard of living for human beings throughout the world. Genetically modified tomatoes and strawberries sit in grocery shelves with longer shelf lives. Genetically modified fish glow in a family’s fish tank and genetically engineered bacteria produce human insulin for use on diabetics. There is no doubt that genetic modification has improved the lives of millions.

Argumentative Essay On Genetically Modified Food

1669 Words | 7 Pages

For years, the health and safety of genetically modified foods have been debated and researched by scientists, but the question still stands: should genetically modified foods be allowed for consumption? The process of genetic modification involves inserting a gene from bacteria or a virus into an organism where it would normally not be found. The purpose is to alter the genetic code in plants and animals to make them more productive or resistant to pests or farming techniques. Genetically modified organisms, more commonly known as GMOs, have been a controversial topic of debate for a number of reasons. The ethics behind genetically modified foods come into question due to an abundance of short and long-term effects from the process, many of which are still unknown today.

This is meant to translate into a product with a lower price, greater benefit either durability, nutritional value or both. An example where a crop has had genetic modification to enhance its nutritional value is in the case of golden rice. (Genetically Modified Organisms , 2013). At first, GM seed developers wanted their products to be recognized by producers which is why they mainly focused on innovations that bring direct benefits to farmers, as well as the food industry in general. GM crops that are on the market presently are specifically aimed at increasing the level of protection on the crops.

GMOs are a very controversial topic now days. Many people are for and against the thought of genetically modifying organisms. You maybe asking yourself, “What is genetically modifying organisms?” I asked myself the same thing, Genetically modifying organisms or GMOs are organisms whose genetic material has been altered using genetic engineering techniques. Therefore this means that it removes organisms, such as bacteria and virus’, from the DNA of a plant or possibly a animal.

A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques (i.e. genetically engineered organism). GMOs are the source of medicines and genetically modified foods and are also widely used in scientific research and to produce other goods. Our study focuses on genetically modified foods like plants and animals and how does the public in the GCC countries. Genetically modified foods or GM foods, also genetically engineered foods, are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering. Genetic engineering is sometimes also called bioengineering or biotechnology.

Technological advancements in the scientific field have led to the advent of genetic engineering, including the genetic modification (GM) of food that may hold the key to the solution of many existing problems like food shortage, world hunger and genetic diseases. Uzogara (2000) state that the intentional attempt to alter the genetic make-up of plants or animals is known as genetic modification. Scientists have shown the potential benefits that those genetically engineered crops can bring about such as increased shelf-life in Flavr Savr Tomato and pest-resistant Bacillus thuringiensis (Bt) corn, which are said to benefit the producers. From the consumers’ point of view, what matters most is the health benefits that genetically engineered crops will bring about, which wild-type food crops may not be able to do.

The modified part is the DNA, and these modifications are often achieved by inserting pieces of the DNA from other organisms into the target ones. This practice has generated a lot of discussions worldwide, and some countries are limitating and even proibiting the import of GMOs because of concerns based upon both ethic and health arguments. In my opinion, health and environment concerns should be carefully examinated before allowing a free diffusion of GMOs, and it is widely agreed that there are not enough information to establish weather or not GMOs are unhealthy or dangerous for the environment. Also, I feel the risk that original species would disappear if OGMs get diffused. Moreover, GMOs are patented, so even their seeds cannot be used without paying royalties, which sounds enough strange to
